Comparatively, the CdS/BiOBr microspheres with s-scheme heterostructure exhibit the surprising photocatalytic performance and CH 3 OH selectivity, which are attributed to the enhanced light absorption, as well as effective separation and migration of the photoinduced electron-hole pairs induced by the s-scheme heterojunction between BiOBr and CdS. This study provides a mild hydrolysis-ultrasonic method for environmental remediation and converting energy using cost-effective semiconductor materials. Recently, converting CO 2 into organic fuels, such as formate, [1] CH 3 OH, [2] CH 4 , [3] and HCHO, [4] is considered as a exploitable solution to improve the pollution of the environment purification and energy demanded.Up to now, numerous methods such as photocatalytic reduction, electrocatalytic reduction, biological transformation,

The discovery of extremely effective heteroatom dopant catalysts for electrochemical reduction reactions is crucial for ambient nitrogen fixation. In this paper, we investigated nitrogen and boron doped biomass carbon as an effective electrocatalyst for nitrogen reduction reaction (NRR), where the N, B content ratio, and pyrolysis temperature were optimized to improve N2 adsorption and N≡N cleavage. The resulting 600ACNB‐213 exhibits outstanding improvement in fixing N2 to ammonia with a high ammonia production rate (41 μg h−1 mg−1 at −1 V vs. RHE), outperforming other metals and carbon‐based materials and even being superior to noble‐metal‐based catalysts. Besides, there indicates good stability through six cycles of testing. Experiments and analyses demonstrated that pyridinic‐N and BC2O were active sites for ammonia synthesis and that their contents' ratio was critical for enhancing ammonia production on N, B doped carbon. These sites can enhance step‐by‐step catalytic reactions through rapid electron transfer processes by strengthening the conductivity of carbon‐based materials with dopants, substantially improving the overall catalytic performance. This research suggests that designing carbon co‐doped with N, B for effective N2 reduction electrocatalysts has a significant potential.
