The authors frame the work as offering a facile synthetic strategy for fabricating robust CoO-based catalysts for efficient CO2 conversion via the RWGS reaction. Catalyst stability at the high temperatures the reaction requires remains a central obstacle, which is why strategies…
A copper nanowire catalyst coated with a covalent organic framework achieved 77 percent Faradaic efficiency for multi-carbon products in CO2 electroreduction, outperforming bare copper nanowires. Subject of Research: Hybrid copper nanowire and covalent organic framework catalysts for electrochemical CO2 reduction to multi-carbon products…

Hitting a copper catalyst with X-rays (yellow) while varying a reaction-triggering voltage (squiggles) revealed the evolution of catalytic reactions (white) on the surface. Newswise — Copper is the most promising catalyst for turning carbon dioxide into valuable chemical feedstocks and liquid…
A new review outlines how atomically precise catalyst interfaces, from dopants and vacancies to curved surfaces and local electric fields, can control which products emerge from electrocatalytic CO2 reduction.
Additionally, the electrocatalytic reduction of CO2 can be integrated with renewable energy sources, such as solar panels or wind power, for sustainable and environmentally friendly CO2 conversion. Therefore, this work is a significant step towards efficiently tackling greenhouse gas emissions and fighting…
High-entropy designs can overcome immiscibility by incorporating multiple elements into a single phase, but the researchers note two drawbacks of that approach. Active sites are often diluted, and structure–property relationships become obscured, making it harder to understand which parts…
Many commercial products, including plasticizers and detergents, rely on aldehyde building blocks. Hydroformylation constructs aldehydes from alkenes and synthesis gas—a mixture of carbon monoxide and hydrogen. The industrial process currently uses rhodium-based catalysts that are expensive, involve toxic phosphine-containing…
Cooling a manganese dioxide electrocatalyst close to water’s freezing point suppressed permanganate-driven degradation more strongly than it reduced oxygen evolution activity, creating a temperature-dependent balance between catalyst activity and lifetime. Cooling an electrolyte to just below 0 °C can extend…
