The porous powdered composites, containing metal halide salts are being used to enhance the storage of cold thermal energy storage (CTES) medium such as ammonia for efficient cooling systems. However, due to the low mass transfer attributable to agglomeration, reduction in pore accessibility, and sample loss, the powdered samples face challenges translating from lab to pilot scale. Conversely, the structuring of composites in beads and pallets can modify the surface chemistry and adsorption mechanism. To investigate the impact of structuring, a comparative analysis of pure, calcium chloride (CaCl2)-impregnated activated carbon (AC) powder and CaCl2-crosslinked AC beads was conducted in this work, to observe the ramification of surface chemistry due to salt distribution, porosity, surface area and pH-controlled crosslinking, on ammonia adsorption. The role of pH in bead formation introduced a new dimension in tailoring ammonia adsorption efficiency. The bead sample containing 20% CaCl2 (AC-B (20%)), with pH-8 crosslinking solution, has shown the two times more ammonia adsorption due to optimum crosslinking, physicochemical interactions and the presence of tuned amount of calcium chloride (CaCl2) on the surface and pores. SEM, XRD, FTIR, BET, DFT, and XPS are used to analyse the fabricated samples before and after the adsorption to thoroughly investigate the adsorption mechanism. The kinetic analysis of experimental results was conducted by applying nonlinear Pseudo 1st order (PFO), Pseudo 2nd order (PSO), and Elovich models, with best fit with N-PSO model confirming the highest mass transfer by the bead sample (AC-B (20%)). Lastly, the economic feasibility analysis as well as the impact of thermal treatment on recovery and sample regeneration was studied by desorbing the best samples at four different temperatures (120 °C, 140 °C, 160 °C, and 180 °C).

Perovskites are of high potential in the ongoing academic research, due to their distinctive electrical properties and crystalline structures. Halide perovskites show high light emissive properties and panchromatic light absorption across the visible spectrum. The exceptional electrical characteristics, such as their long carrier lifespan, high diffusion length, and charge carrier mobility, allow the electric charges to be transported and collected effectively. Furthermore, by tuning the cations and anions composition, perovskite's opto-electrical properties can be altered. Moreover, dimension reduction affects their band gap and intrinsic features to induce higher structural stability but at the cost of the quantum confinement effect. Owing to their exceptional properties, halide perovskites are being researched in energy-related and semiconducting applications, hold high promise and the future looks bright. But challenges remain, and the larger question is what needs to be done to make them more stable.
