The electrochemical oxidative cleavage of C(OH)-C bonds facilitates the conversion of lignin-derived secondary alcohols and ketones into valuable carboxylates in a mild and environmentally friendly manner. In this study, we present efficient and cost-effective FeNi layered double-hydroxide (LDH) nanosheets created through a one-step galvanostatic electrodeposition on nickel foam (NF). The FeNi-LDH/NF shows a high activity for α-phenethyl alcohol (α-PEA) electrooxidation reaction leading to low potential 1.489 V vs. RHE to reach a current density of 100 mA cm−2, α-PEA was almost completely transformed, and the yield of benzoic acid (BA) was high (> 95%). Both theory and experiments show that α-PEA is first oxidized to acetophenone and then to benzoic acid. The dehydrogenation and oxygenation of the C–H bond is the rate-limiting step of the reaction. In addition, an energy-saving and multifunctional flow electrolytic cell has been developed successfully, througn coupling α-PEA electrooxidation reaction with hydrogen evolution reaction, with FeNi-LDH/NF as dual-functional electrocatalyst. The flow electrolytic cell can operate stably for 200 h.
C(OH)-C键的电化学氧化裂解有助于木质素衍生的仲醇和酮以温和和环保的方式转化为有价值的羧酸盐。在这项研究中，我们通过一步恒流电沉积在泡沫镍（NF）上制备了高效且具有成本效益的FeNi层状双氢氧化物（LDH）纳米片。FeNi-LDH/NF对α-苯乙醇（α-PEA）具有较高的电氧化反应活性，相对于RHE电位为1.489 V，电流密度为100 mA cm−2，α-PEA几乎完全转化，苯甲酸（BA）收率高（95%）。理论和实验都表明，α-PEA首先被氧化为苯乙酮，然后被氧化为苯甲酸。C-H键的脱氢和氧化是反应的限速步骤。此外，通过α-PEA电氧化反应与析氢反应耦合，以FeNi-LDH/NF为双功能电催化剂，成功研制出节能多功能流动电解槽。流动电解槽可稳定运行200 h。

CC bond cleavage in alkynes provides a powerful strategy for the functional group transformation of alkyne compounds, but it is challenging to balance reactivity and selectivity due to its high bond dissociation energy and inherently complex reaction pathways. In this work, we report the use of commercially available nitrates in acetonitrile for the mild aerobic oxidative cleavage of the alkyne CC bonds, resulting in the formation of carboxylic acids with good to excellent yields. This approach demonstrates broad functional group tolerance, applicable to those unactivated alkynes and substrates containing oxidation-sensitive groups. Mechanistic studies using EPR, FT-IR, and NMR measurements reveal that the excellent catalytic property arises from the formation of coordination intermediates between the alkyne and zinc nitrate, stabilized by acetonitrile through ion–dipole interactions. This stabilization promotes alkyne activation, facilitates the oxygen atom transfer (OAT) from nitrate to the CC bond and reduces the nitrate to nitrogen oxides, which then act as free-radical initiators to trigger a chain reaction and accelerate the oxidative cleavage of the CC bond, with molecular oxygen serving as the terminal oxidant.

Hydrogen borrowing amination provides a sustainable alcohol-based N-alkylation method for the amine synthesis and functionalization, yet the development of non-noble metal catalysts that are effective under additive- and solvent-free conditions remains a huge challenge. Herein, we report a Cobalt (Co)-containing zeolite, Co@Beta, prepared by directly encapsulating defect Co sites within BEA framework via an acid co-hydrolysis route. Co@Beta shows excellent catalytic performance in the N-alkylation of benzyl alcohol with aniline, achieving > 92% yield and a turnover frequency (TOF) of 466 h−1 without external solvent or additive. The catalyst is stable during the recycling amination and extendable to the amination between various aromatic alcohols and amines. In situ spectroscopic analysis, theoretical calculations, as well as step-by-step comparison with post-loaded analogues, reveal that defect Co sites within Co@Beta are active centers, thereby lowering the energy barrier for the rate-determining dehydrogenation step and underpinning the superior amination performance.

The separation and transport efficiency of photogenerated charge carriers are critical factors determining the photocatalytic performance of semiconductors. However, the lack of a direct and effective driving force for charge separation leads to rapid recombination of most photogenerated carriers within the bulk or on the surface of photocatalysts, severely limiting their output efficiency. Constructing an internal polarization electric field to drive the directional migration of charges and suppress carrier recombination has been demonstrated as an effective strategy. In this study, we designed and synthesized two conjugated polymers with distinct symmetries via a local π-skeleton modulation strategy of molecular units. We systematically clarified the regulatory mechanism underlying the disruption of molecular structural unit symmetry on the photocatalytic charge transport process. Both experimental results and theoretical calculations demonstrated that the breaking of molecular unit symmetry induces an internal electric field within the photocatalyst, which provides an intrinsic driving force for the directional migration and rapid accumulation of electrons. This process establishes a continuous π-electron delocalization channel, creating a “charge superhighway”, while reducing the exciton binding energy (Eb) to significantly suppress carrier recombination, thereby substantially enhancing the photocatalytic performance. This study demonstrates the polarization effect caused by the disruption of molecular unit symmetry, which can amplify the electric field strength to optimize charge separation and provide a design option for high-efficiency organic photocatalysts.

The treatment of nitrate (NO3−) pollutants is of critical importance for both human health and sustainable environmental development. The efficient conversion of low-concentration NO3− is mainly challenged by the competing hydrogen evolution side reactions and the lack of efficient hydrogen sources for deep hydrogenation. Here, we report a redox-enhanced photocatalytic system by constructing spatially separated CuxO nanoclusters (CuxO NCs) and oxygen vacancies (OVs) as dual active sites on a TiO2 nanotube support. CuxO NCs, as electron enrichment centers, significantly enhance the adsorption and activation capabilities for NO3−, thereby enabling NO3− to be activated into the key intermediate nitrite (NO2−). OVs, as efficient hole-trapping sites, accelerate the oxidation half-reaction, promoting the generation of highly reactive hydrogen radicals (H). Most importantly, the directional addition of the H to NO2− facilitates its deep reduction via a H-mediated pathway, leading to the highly selective generation of ammonia (NH3). Almost 100 % of the NO3− conversion ratio and a competitive NH3 selectivity (98.3 ± 0.16 %) are achieved in this system. This study highlights the critical roles of NO3− activation and H in efficient NO3− conversion, providing an innovative strategy for the resource utilization of NO3−-contaminated wastewater.
Environmental Implication: A redox-enhanced photocatalytic system is constructed to enable efficient activation of NO3− to NO2− and subsequently H-mediated hydrogenation. As a result, nearly complete NO3− removal ratio (∼100 %) with high selectivity toward NH3 (98.3 ± 0.16 %) is achieved. This study provides insights and guidance for the efficient conversion and resource utilization of low-concentration NO3−, significantly advancing the application of photocatalytic technology in environmental remediation and resource recovery. It also offers support for the establishment of a sustainable nitrogen cycle system.
