We present an effective way to develop superhydrophobic steel surface which shows stable superhydrophobicity under harsh mechanical bending.

Hydrogen production using novel catalysts is regarded as one of the most needed technology for the future economic needs and water splitting to give H₂ gas, which is a challenging task for large-scale production. This work reports the synthesis of Meso-Cu-BTC metal organic framework and further used for understanding its role in electrochemical hydrogen evolution reaction (HER) in 1 M NaOH solution. Meso-Cu-BTC electrocatalyst showed a less overpotential of 89.32 mV and an onset potential of 25 mV with an appreciable current density. Results show a low Tafel slope of 33.41 mVdec⁻¹ and long-term durability. Thus, the overall results show that Meso-Cu-BTC acted as a good candidate for electrocatalysis towards hydrogen evolution.
