Abstract

fetched live from OpenAlex

Abstract 2D materials are regarded as promising electrocatalysts for water splitting because of their advances in providing ample active sites and improving electrochemical reaction kinetics. 2D MoSe 2 has a greater intrinsic electrical conductivity and lower Gibbs free energy for reactant adsorption. However, there is still room for improvement in the electrocatalytic performance of MoSe 2 for high‐performance electrochemical water splitting devices. Herein, the in situ preparation of heterostructure made of covalently bonded MoSe 2 and rGO is reported. The obtained electrocatalyst contains the aggregated 3D structured MoSe 2 over rGO, which is covalently bonded together with more edge sites. The active edge sites of MoSe 2 /rGO are dynamically involved in the electrocatalytic activity while facilitating electron transfer. Hence, the MoSe 2 /rGO heterostructure requires a low cell voltage of 1.64 V to reach 100 mA cm −2 in water splitting with high reaction kinetics. The aggregated MoSe 2 over rGO with more edge sites exposed by the 3D structure of MoSe 2 and the interfacial covalent bond in between them provides a favorable electronic structure for the HER and OER with low overpotentials and high current densities and enhances the stability of the electrocatalyst. This work presents an attractive and cost‐effective electrocatalyst suitable for industrial‐scale hydrogen fuel production.

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
