Developing economical, efficient, and earth-rich electrocatalysts for hydrogen evolution reaction (HER) is quite challenging ideal. We propose that [P2W18O62]6– as the guest, due to its excellent reversible 18 electron-transfer capacity redox properties, then TM-BDC (TM = Ni, Co, Fe, BDC 1,4-benzene-dicarboxylate) host make packaged not escape porous structure. Benefiting from strong redox-competent interactions between structures of full exposure abundant active sites, three {P2W18}@TM-BDC composites exhibited HER activity, with {P2W18}@Ni-BDC requiring 198 mV (overpotentials) 104 mV/dec (Tafel slope) HER. More importantly, show stability, voltage remaining nearly constant 24 h. Meanwhile, linear sweep voltammetry (LSV) electrochemical impedance spectroscopy (EIS) curves overlap well initial curve after stability test. Our work offers a promising strategy synthesizing high-performance broadens scope nonprecious metal composite material preparation.

Abstract Photocatalytic CO 2 reduction reaction (CO RR) into high‐value‐added fuels has received significant attention, yet multiple electron and proton processes involved in RR result low selectivity. Herein, a strategy involving oxygen vacancies (Ovs)‐enriched Bi MoO 6 coated on ZIF‐67‐derived Co 3 O 4 to construct well‐defined core‐shell nanocage is developed, which drives effective photoconversion CH with nearly 100% selectivity high apparent quantum efficiency of 2.5% at 420 nm pure water under simulated irradiation. Theoretical calculations experiments exhibit that the potential difference stemming from built‐in electric field provides guarantee for occurring H oxidation set . Numerous exposed Ovs formed Bi─O bond by ethylene glycol mediated approach promotes adsorption charge separation efficiency, can optimize kinetics thermodynamics, facilitating hydrogenation key intermediate *CO generate This work new controlled vacancy generation photocatalysts achieve high‐performance methanation.

Abstract The photocatalytic conversion of CO 2 into products such as CH 4 and C H 6 poses a significant challenge due to the lengthy reaction steps high energy barrier involved. In this study, both benzothiadiazole (BTD) hydroxyl groups (‐OH) are introduced cobalt‐based polymerized porphyrinic network (PPN) through C‐C coupling reaction. This modification orbital levels that strengthens ability gain electrons facilitates charge transfer in PPN. Hydroxyl group largely enhances for light response, while thiadiazole unit tunes molecular proper level. By way, BTD‐DBP‐PPN(Co) achieves capability under irradiation light. Co active site is reduce facilitate transfer. pathway production has been studied further mechanism explanation. Overall, series porphyrin centers with donor–acceptor (D‐A) structure designed synthesized enhance reduction performance achieve formation 300‐W Xe lamp irradiation.
