Cooperative promotion of electroreduction of CO to -propanol by *CO enrichment and proton regulation.

The CO/CO electroreduction reaction (CORR/CORR) to liquid products presents an enticing pathway to store intermittent renewable electricity. However, the selectivity for desirable high-value C products, such as -propanol, remains unsatisfactory in the CORR/CORR. Here, we report that *CO enrichment and proton regulation cooperatively enhance C-C coupling by increasing CO pressure and utilizing proton sponge modification, promoting the production of -propanol over a Cu/Cu nanosheet catalyst in the CORR.

Selective Gold Recycling from Electronic Waste Using a Highly Stable Porous Aromatic Framework/Polymer and Its Application for CO Electroreduction.

Recycling gold from electronic waste represents a sustainable and environmentally friendly strategy for both resource recovery and waste reduction. In this study, we designed an innovative and highly stable porous aromatic framework (PAF)/polymer composite, PAF-147/polydopamine (PDA), as an efficient adsorbent for selective gold recovery for the first time. The maximum gold adsorption capacity of PAF-147/PDA reached 1700 mg g.
