Specifically, fossil fuels are at the forefront of such an extraordinary advancement until now.

Stacking Polytypes of 1T′ Phase Se-Rich Transition Metal Diselenide and Their Electrocatalytic Activity of Hydrogen Evolution Reaction Transition metal dichalcogenides exhibit various stacking polytypes and distinct electronic structures. In this study, first-principles calculations show that chalcogen enrichment induces the phase conversion from 2H to 1T′.
