 The abstract states that it is important to develop more efficient and cost-effective bifunctional electrocatalysts for oxygen-slash-hydrogen evolution reactions, OER slasher. It also explains how a new type of binder-free hollow TO2 at Cone 9S8 core branch arrays was created using a facile and powerful sulfurization strategy. This new material has been shown to have exceptional electrocatalytic performance with low overpotentials of 240 and 139 mV at 10 mA Cm, 2 and low taffle slopes of 55 and 65 mV December 1 for OER and her in alkaline medium, respectively. Furthermore, this material can be used as both cathode and anode in an electrolysis cell, resulting in a remarkably low water splitting voltage of 1.56 V at 10 mA Cm, 2 and long-term durability without any decay after 10 days.
