“…As a result, nanobelt structures exhibit superior catalytic performance. In addition to designing the morphology of an electrocatalyst to increase the number of active sites, various modification strategies have been explored to optimize its electronic structure and further enhance its catalytic activity such as heteroatom doping, 16 vacancy engineering, 17 interface engineering, 9 and phase engineering. 18 Heteroatom doping is a widely used approach to modify the electronic structure of electrocatalysts, increase their polarity, and create new active phases.…”
