WebAdenosine triphosphate (ATP) is an organic compound that provides energy to drive and support many processes in living cells, such as muscle contraction, nerve impulse … To fabricate the IMO with electron-deficient surface, the electrospinning synthetic scheme was designed for the IMO precursor (Fig. 1a). Consequently, the nanocomposite fiber of IMO precursor is formatted in the rotating collector using PVP substrate. PVP, firstly proposed as “polyol reduction” for … See more X-ray diffraction (XRD) patterns of IMO (Fig. 2a) indicated that phase properties of iridium are metallic as assumed above. The XRD pattern of IrO2-MoO3 (IOMO) … See more To probe surface compositions and determine the oxidation states, we performed X-ray photoelectron spectroscopy (XPS) analyses. The survey spectra of IMO … See more IMO outperforms other OER catalysts previously reported in the literature, including benchmark catalysts such as RuO2 (10 mA cm−2 at ~293 mV, similar to … See more Inspired by the unique structure with the electron-deficient surface that benefits the OER efficiency as demonstrated using in situ and ex situ x-ray … See more WebThe shuttle effect caused by soluble LiPSs leads to Li-S batteries with extremely low coulombic efficiency and poor cycling stability, which seriously limits their large-scale application. The introduction of reasonable catalytic materials into the S cathode to anchor the LiPSs is an effective strategy to alleviate this problem. cyprus thompson creek
