Abstract Electrocatalytic conversion of CO 2 to formic acid (HCOOH) represents a promising approach for storing renewable energy and addressing the challenges hydrogen storage transportation. Palladium (Pd) is only known metal capable achieving this process at nearly zero overpotential. However, its practical applications are severely limited by evolution reaction (HER) competition poisoning. Bimetallic alloys, especially intermetallics with ordered structures, offer an effective way optimize performance due their unique catalytic properties. Here, PdBi alloys synthesized structures adjustable ratios active sites efficient electroreduction HCOOH. The o ‐PdBi alloy effectively suppresses both HER production during reduction process, ≈95% HCOOH selectivity across wide range current densities excellent stability industrial‐level densities. Additionally, structure facilitates high maintenance while mitigating overpotential, resulting in cell voltage 2.65 V 200 mA cm −2 . These findings provide pathway application Pd‐based catalysts electroreduction.

Abstract Formic acid (FA) has emerged as a promising candidate for hydrogen energy storage due to its favorable properties such low toxicity, flammability, and high volumetric capacity under ambient conditions. Recent analyses have suggested that FA produced by electrochemical carbon dioxide (CO 2 ) reduction reaction (eCO RR) using low‐carbon electricity exhibits lower fugitive (H emissions global warming potential (GWP) during the H carrier production, transportation processes compared those of other alternatives like methanol, methylcyclohexane, ammonia. eCO RR can enable industrially relevant current densities without need pressures, temperatures, or auxiliary sources. However, widespread implementation is hindered requirement highly stable selective catalysts. Herein, aim explore evaluate catalyst engineering in designing nanostructured catalysts facilitate economically viable production FA.

Abstract Electrochemical CO 2 reduction reaction (CO RR) offers a promising approach to close the carbon cycle and reduce reliance on fossil fuels. However, traditional decoupled RR processes involve energy‐intensive capture, conversion, product separation, which increases operational costs.

Abstract A considerable challenge in CO 2 reduction reaction (CO RR) to produce high‐value‐added chemicals comes from the adsorption and activation of form intermediates. Herein, an amino‐induced spillover strategy aimed at significantly enhancing capabilities CdS supported on N‐doped mesoporous hollow carbon sphere (NH −CdS/NMHCS) for highly efficient RR is presented. The prepared NH −CdS/NMHCS exhibits a high Faradaic efficiency (FE ) exceeding 90% −0.8 −1.1 V versus reversible hydrogen electrode (RHE) with highest FE 95% −0.9 RHE H cell. Additional experimental theoretical investigations demonstrate that alkaline −NH group functions as potent trapping site, effectively adsorbing acidic , subsequently triggering CdS. amino modification‐induced spillover, combined electron redistribution between NMHCS, not only readily achieves spontaneous * COOH but also greatly reduces energy required conversion intermediate, thus endowing improved kinetics reduced overpotential ‐to‐CO conversion. It believed this research can provide valuable insights into development electrocatalysts superior application.
