Abstract

Supported metal catalysts have been widely applied and commonly fabricated through the H₂ reduction process. Herein, we develop a H₂-free room-temperature discharge-driven reduction (RT-DR) reactor for fabricating supported metal catalysts at room temperature without H₂. By RT-DR reactor, a catalyst with pseudo-boehmite (PB) as support (CdS/Pt/PB) is fabricated. In visible-light-driven photocatalytic H₂O splitting to H₂, CdS/Pt/PB shows a H₂ evolution rate of 1132 μmol h⁻¹, which is greatly enhanced than that on catalyst prepared by traditional H₂-reduction (633 μmol h⁻¹). RT-DR reactor is also used to prepare a catalyst with low sodium PB (LSPB) as support (CdS/Pt/LSPB). In visible-light-driven photocatalytic H₂O splitting to H₂, CdS/Pt/LSPB shows a H₂ evolution rate of 2554 μmol h⁻¹, which is 2.5 times higher than that on catalyst prepared by traditional H₂-reduction (1029 μmol h⁻¹). Thus, RT-DR reactor has high efficiency and universality in preparing catalysts, thus offering a great potential for commercialization.

期刊介绍： The AIChE Journal is the premier research monthly in chemical engineering and related fields. This peer-reviewed and broad-based journal reports on the most important and latest technological advances in core areas of chemical engineering as well as in other relevant engineering disciplines. To keep abreast with the progressive outlook of the profession, the Journal has been expanding the scope of its editorial contents to include such fast developing areas as biotechnology, electrochemical engineering, and environmental engineering. The AIChE Journal is indeed the global communications vehicle for the world-renowned researchers to exchange top-notch research findings with one another. Subscribing to the AIChE Journal is like having immediate access to nine topical journals in the field. Articles are categorized according to the following topical areas: Biomolecular Engineering, Bioengineering, Biochemicals, Biofuels, and Food Inorganic Materials: Synthesis and Processing Particle Technology and Fluidization Process Systems Engineering Reaction Engineering, Kinetics and Catalysis Separations: Materials, Devices and Processes Soft Materials: Synthesis, Processing and Products Thermodynamics and Molecular-Scale Phenomena Transport Phenomena and Fluid Mechanics.
