"Carbon nanotubes encapsulated transition metals for efficient hydrogen" by Y. Han, X. Mao et al.

Carbon materials are widely used in various industrial applications due to their outstanding stability and robustness in diverse structures, yet it remains a revolutionary and challenging task in activating low-cost carbon materials for efficient catalysis. Herein, inspired by the successful experimental synthesis, we for the first-time exploited carbon nanotubes (CNTs) encapsulated transition metal (TM) atoms (TM@CNTs) for hydrogen evolution reaction (HER) using density functional theory (DFT) calculations. The Gibbs free energy of the H–C bond on the pristine CNTs is too positive, which prevents the adsorption of H atoms. However, TM@CNTs (TM = Fe, Co, Ni) have superior HER activity than those widely recognized Pt and MoS2 catalysts, benefiting from disrupting the π conjugations and activating the stable sp2 hybridizations among carbon atoms in CNTs. A new set of metal-free catalytic surfaces with strong HER activity have been developed. Meanwhile, the HER activity of graphene nan ....

"Guanidine-based biomimetic hydrides for carbon dioxide reduction" by Junbo Chen, Haibo Yu et al.

The feasibility of various bespoke guanidine-based compounds as biomimetic hydrides were assessed by Density Functional Theory (DFT). The results predicted that tricyclic pentanidine hydrides are viable candidates to reduce CO2 to HCOO− and be regenerated electrochemically, demonstrating a recyclable and sustainable method to achieve metal-free electrochemical reduction of CO2 ....
