Highly efficient and selective extraction of gold by reduced graphene oxide

Fei Li et al.

Summary: This study demonstrates the excellent performance of reduced graphene oxide (rGO) in extracting gold from e-waste, even at minute concentrations. By controlling the protonation of the oxidized regions of rGO, gold can be extracted exclusively, without contamination by other elements.

Catalytic activity of graphene-covered non-noble metals governed by proton penetration in electrochemical hydrogen evolution reaction

Kailong Hu et al.

Summary: The study reveals that increasing the number of graphene-covering layers significantly alters the hydrogen evolution reaction performances of nickel and copper, while graphene-covering technology provides a promising approach to achieve a non-noble-metal catalyst with corrosion protection and catalytic activity under acidic media.

Exponentially selective molecular sieving through angstrom pores

P. Z. Sun et al.

Summary: Researchers have successfully demonstrated the creation of angstrom-sized pores in monolayer graphene through low intensity exposure to low kV electrons, through which helium and hydrogen can permeate easily while larger species like xenon and methane are blocked. Gas transport through these pores experience activation barriers that increase quadratically with molecules' kinetic diameter.

Operando visualization of the hydrogen evolution reaction with atomic-scale precision at different metal-graphene interfaces

Tomasz Kosmala et al.

Summary: The study found that thin iron films covered with monolayer graphene exhibit superior catalytic activity for the hydrogen evolution reaction compared to platinum. By evaluating noise in the tunnelling current of electrochemical scanning tunnelling microscopy, researchers discovered the exceptional activity of single iron atoms trapped within carbon vacancies and curved graphene areas on step edges. Density functional theory calculations further confirmed this sequence of activity.
