Abstract Active carbons have unique physicochemical properties, but their conductivities and surface to weight ratios are much poorer than graphene. A facile method is innovated chemically process biomass by “drilling” holes with H 2 O exfoliating into graphene‐like nanosheets HAc, followed carbonization at a high temperature for highly graphitized activated carbon greatly enhanced porosity, pore structure, conductivity, large area. This exhibits extremely specific capacitance (340 F g −1...
Single-atom catalysts have demonstrated their superiority over other types of for various reactions. However, the reported nitrogen reduction reaction single-atom electrocatalysts exclusively utilize metal-nitrogen or metal-carbon coordination configurations as catalytic active sites. Here, we report a Fe electrocatalyst supported on low-cost, nitrogen-free lignocellulose-derived carbon. The extended X-ray absorption fine structure spectra confirm that atoms are anchored to support via...
The development of efficient electrocatalysts to generate key *NH2 and *CO intermediates is crucial for ambient urea electrosynthesis with nitrate (NO3- ) carbon dioxide (CO2 ).

Electronic conduction can accelerate charge transfer, and metal–support interactions help improve the ability to resist CO poisoning, which are important features in methanol oxidation reaction (MOR) catalysis. Thus, an effective support that allows modulation of electronic is highly desired for catalyst construction.
