Hierarchical MoS2–rGO nanosheets with high MoS2 loading with enhanced electro-catalytic performance

Ionic-liquid mediated synthesis of molybdenum disulfide/graphene composites: An enhanced electrochemical hydrogen evolution catalyst

“…Hu et al also prepared MoS 2 /RGO (reduced graphene oxides) composites by a similar solvothermal route using dimethyl-formamide as solvent, which exhibited better HER performance [12]. Zhou et al designed and prepared the hierarchical MoS 2 erGO nanosheets with enhanced HER performance [13]. For these MoS 2 /graphene composites prepared by solvothermal or hydrothermal route, graphene can not only be used as ideal platform for the selective growth of MoS 2 crystals with small layers, but also greatly increase the conductance of the composites.…”

In situ Integration of a Metallic 1T‐MoS2/CdS Heterostructure as a Means to Promote Visible‐Light‐Driven Photocatalytic Hydrogen Evolution

“…Various morphological 2H‐MoS 2 nanomaterials prepared by a hydrothermal or impregnation sulfidation method have shown high activities for hydrogen evolution, owing to the high H 2 activation ability of their edges . Complementary to the low charge‐transport mobility of the 2H phase, graphene with high mobility is often added as graphene–MoS 2 cocatalysts to provide charge‐transfer channels to prevent electron–hole recombination . Recently, further improvements in the hydrogen evolution reaction (HER) kinetics by chemically exfoliating 1T‐MoS 2 nanosheets through a self‐ assembly approach and by intercalating ammonium ions into 1T‐MoS 2 by physical mixing have also been reported .…”

Enhanced closed loop voltage control of buck converter for improved performance

“…(4), and the output voltage ripple is described by Eqs. (5) and (6). Note that as the switching frequency increases, the minimum size of the inductor to produce continuous current and the minimum size of the capacitor to limit output ripple both decrease [15].…”

“…To improve the load transient response, two-loop voltage control technique was proposed. Analysis and simulation results show that twoloop voltage control technique has much faster transient response than conventional current mode control or voltage mode control techniques [2][3][4][5][6]. Two-loop voltage mode control (TVMC) [4] has been widely adopted by the power supply because of its unique features of fast transient response and simple compensation.…”

“…Literature [4] shows the two-loop voltage control architecture to have a faster transient response compared to voltage mode and current mode control mechanisms. Power demands of computing and telecom applications are driving rapid developments in semiconductor components for power conversion [5]. Thus the obvious choice of control mechanism for the next generation extreme temperature DC-DC systems is two-loop voltage control architecture.…”
