The photocatalytic nitrogen reduction reaction (NRR) in aqueous solution is a green and sustainable strategy for ammonia production. Nonetheless, the efficiency of process still has wide gap compared to that Haber–Bosch one due difficulty N2 activation quick recombination photo-generated carriers. Herein, core-shell Bi@Bi2MoO6 microsphere through constructing Schottky junctions been explored as robust photocatalyst toward NH3. Metal Bi self-reduced onto Bi2MoO6 not only spurs electron hole separation owing junction at interface but also promotes adsorption active sites synchronously. As result, yield N2-to-ammonia conversion reaches up 173.40 μmol g−1 on photocatalysts, much two times bare Bi2MoO6. This work provides new design decarbonization by utilization renewable energy sources.

Regulating the Electronic Structure of Biobr by Cu-Doping to Promote Efficient Photocatalytic Nitrogen Fixation Reaction

Published: Jan. 1, 2025

Abstract: Element doping is critical in regulating the electronic structure to enhance N2 adsorption, opening up new possibilities for achieving highly efficient photocatalytic nitrogen reduction reactions (pNRR). In this study, we successfully prepared Cu-doped BiOBr (Cu-BiOBr) operating a simple solvothermal method. Density Functional Theory (DFT) calculations and experimental investigations were employed explore how Cu influences performance of pNRR over BiOBr. The DFT analysis indicates that alters structure, lowers energy barrier reaction, narrows bandgap. This adjustment leads remarkable NH3 production rate 466.3 μmol⋅gcat−1⋅h−1 without need sacrificial agents 2% Cu-BiOBr sample. addition, based on findings in-situ FTIR, detailed mechanism adsorption/activation hydrogenation reaction N ≡ bonds was proposed. research introduces prospective way designing transition metal-doped catalysts with regulated structures pNNR, which has significant implications advancing other material systems.

Abstract Photocatalytic nitrogen fixation has evolved as potential sustainable technique for producing ammonia in contrast to Haber‐Bosch (HB) process. In this process, semiconductor‐based materials are utilized the presence of light and water, thereby making it less energy‐intensive more eco‐friendly. However, photocatalytic have several disadvantages, including limited chemisorption activation nitrogen, low absorption, rapid charge recombination, sluggish kinetics. To overcome these issues, design catalyst tailoring active surface sites vital so that enhanced performance can be achieved. Also, there is debate about correct determination due interference by nitrogenous impurities. Taking all factors into consideration, review examines recent reports on defects modified (vacancy doping), facet‐engineered, heterojunction‐based catalysts fixation. The different quantification techniques like Nessler's reagent, indophenol method, ion chromatography (IC), etc. been discussed detail along with issues associated them. Finally, existing challenges outlook emerging technology presented. It expected will assist researchers understanding current state field effectively implementing pave way future advancements.
