High-entropy borides hold potential as electrocatalysts for water oxidation. However, the synthesis of tailored nanostructures remains a challenge due to thermodynamic immiscibility polymetallic components. Herein, FeCoCuMnRuB nanobox decorated with nanosheet array was synthesized first time by "coordination-etch-reduction" method. The has various structural characteristics express catalytic performance; meanwhile, it combines high-entropy effect multiple components electron trap induced electron-deficient B, synergistically regulating its electronic structure. As result, exhibits enhanced OER activity low overpotential (η10 = 233 mV), high TOF value (0.0539 s–1), small Tafel slope (61 mV/dec), and satisfactory stability 200 h, outperforming alloy low-entropy borides. This work develops entropy B-driven strategy motivating performance oxidation, which broadens diversity category materials.

Recently, two-dimensional transition metal borides (2D MBenes) have demonstrated advanced physical, mechanical, and electrochemical performance; however, there are fewer studies in the literature. In particular, 2D molybdenum boride MoB), created from aluminum (MoAlB, MAB phase), is one of important materials introduced due to its thermodynamically stable structure.

Rechargeable Li–S batteries (LSBs) are emerging as an important alternative to lithium‐ion (LIBs), owing their high energy densities and low cost; yet sluggish redox kinetics of LiPSs results in inferior cycle life.
