Recent COVID-19 pandemic has raised an urgent need for effective strategies to combat viruses that can pose serious health threats to the entire human race. Incorporating antipathogenic functions into everyday objects and personal protective equipment has become increasingly important, motivating the development of general-purpose antiviral materials. Single-atom catalysts, known for superior catalytic performance and maximized atomic utilization, have been explored in various research fields, including artificial nanozymes for bioapplications. We present reduced graphene oxide (rGO)-supported Fe-N single-atom catalyst-based nanozyme (Fe-N-rGO) capable of achieving 99.99% viral deactivation against influenza A virus, outperforming bulk and nanoscale counterparts. The antiviral mechanism is attributed to the strong adsorption of hemagglutinin on the viral surface, leading to protein denaturation along with the potential generation of reactive oxygen species. Additionally, Fe-N-rGO with 1 wt % can be uniformly coated onto arbitrary substrates, well-maintaining the strong antiviral performance.

Progress towards a hydrogen economy depends on green and efficient ways to produce hydrogen. A promising route is the catalytic hydrolysis of ammonia borane (AB). To address challenges in catalyst performance and cost for AB hydrolysis, we developed a structurally tuned heterogeneous non-precious metal catalyst based on cobalt (Co) and copper (Cu).

To address the sluggish kinetics of CO reduction and release reactions and poor cycling stability in lithium-carbon dioxide batteries, this study proposes a bifunctional catalyst based on a rare-earth monometallic catalyst anchored with Janus MoSSe. Through density functional theory calculations and transition state analysis, the Dy-S@MoSSe catalyst was selected with a total overpotential of only 1.00 V, which is superior to graphene and commercial carbon nanotubes.

Fe-N-C catalyst is the most promising non-noble metal oxygen reduction catalyst for proton-exchange membrane fuel cells (PEMFCs); however, their practical applications are still limited by unsatisfactory long-term stability. This is because the N atoms of the active FeN moiety are easy to protonate, leading to the leaching of Fe atoms, and the HO generated during oxygen reduction reaction (ORR) process triggers the Fenton reaction, further accelerating the dissolution of Fe. To address these critical stability challenge, we developed a general strategy to transform FeN single-atom sites to FeN dual-atom sites in Fe-N-C catalysts with various carbon substrates.
