Rechargeable zinc–air batteries typically require efficient, durable, and inexpensive bifunctional electrocatalysts to support oxygen reduction/evolution reactions (ORR/OER). However, sluggish kinetics and mass transportation challenges must be addressed if the performance of these catalysts is to be enhanced. Herein, a strategy to fabricate a catalyst comprising atomically dispersed iron atoms supported...
The facile creation of high‐performance single‐atom catalysts (SACs) is intriguing in heterogeneous catalysis, especially on 2D transition‐metal dichalcogenides. An efficient spontaneous reduction approach to access atomically dispersed iron atoms supported over defect‐containing MoS2 nanosheets is herein reported. Advanced characterization methods demonstrate that the isolated iron atoms situate...
The development of earth‐abundant, active, and stable catalysts is important for solar energy conversion. Metal‐organic frameworks (MOFs) have been viewed as a promising class of porous materials, which may have innovative application in photocatalysis. In this paper, three types of Fe‐based MOFs and their aminofunctionalized derivatives have been fabricated and systematically studied as water oxidation...
An improved nonlinear model of switched reluctance motor with losses for use in control system has been presented in order to improve the accuracy of the model. The specific requirement was separating the data of losses and the data without losses. The equivalent circuit of measuring flux has been analyzed and a virtual iron loss resistance formula has been deduced. Based on the sample data, an analytic...
