A scalable, and cost-effective method was employed to prepare self-supported CuSn bimetallic catalyst on carbon paper. The obtained CuSn catalyst demonstrates high faradaic efficiency of CO around or above 90% at a broad potential range from -0.7 to -1.8 V reversible hydrogen electrode, greatly surpassing Cu or Sn counterparts.

Article Synopsis
- The study explores using electrodeposited copper (Cu) and tin (Sn) in electrocatalysts to efficiently reduce atmospheric CO and produce valuable products while integrating with renewable energy.
- The research focuses on different configurations of Cu and Sn, finding that a catalyst with Sn over a thin layer of Cu performs best, demonstrating promising durability in initial tests.
- Optimized Sn and Cu-based catalysts yield over 60% organic products, mainly CO, at low energy costs (under 3 V), highlighting the process's economic viability.

Electrocatalytic CO reduction reaction (CORR) is a process in which CO is reduced to high-value-added C and C energy sources, particularly ethylene (CH), thereby supporting carbon-neutral recycling with minimal consumption. This makes it a promising technology with significant potential. Nevertheless, the low selectivity for CH remains a significant challenge in practical applications.

In the electrochemical CO reduction reaction (CORR), Cu alloy electrocatalysts can control the CORR selectivity by modulating the intermediate binding energy. Here, we report the thermodynamic-based Cu-Sn bimetallic phase control in heterogeneous catalysts for selective CO conversion. Starting from the thermodynamic understanding about Cu-Sn bimetallic compounds, we established the specific processing window for Cu-Sn bimetallic phase control.

In this work, the solvothermal solidification method has been used to be prepared as a homogenous CuSn-organic nano-composite (CuSn-OC) to use as a catalyst for alkaline water electrolysis for cost-effective H generation. FT-IR, XRD, and SEM techniques were used to characterize the CuSn-OC which confirmed the formation of CuSn-OC with a terephthalic acid linker as well as Cu-OC and Sn-OC. The electrochemical investigation of CuSn-OC onto a glassy carbon electrode (GCE) was evaluated using the cyclic voltammetry (CV) method in 0.

The electrocatalytic C-N coupling from carbon dioxide and nitrate under ambient conditions is kind of sustainable and promising alternative method for urea synthesis. To date, the influence of catalyst surface properties on molecular adsorption configuration and electrocatalytic urea synthesis activity is unclear. In this work, we proposed that the urea synthesis activity is closely linked with the localized surface charge on bimetallic electrocatalysts, it is found that a negatively charged surface induces C-bound path and boosts urea synthesis.
