Transition metal dichalcogenides(TMDs),with the general formula MX_(2)(M=Mo/W/Fe/Co/Ni,etc.;X=S/Se/Te),have attracted extensive research interests for hydrogen evolution reaction(HER).Compared with numerous studies on noble-metal-free TMDs,the chalcogen-dependent HER catalytic properties of noble-metal-based TMDs are lack of sufficient research ***,a facile electrospinning-assisted synthetic strategy is proposed to synthesize ruthenium dichalcogenides(RuX_(2),X=S/Se/Te)nanoparticles decorated carbon nanofibers(CNFs).Benefiting from the identical nanofibrous morphology and exposed crystal planes of RuX_(2)(111),the catalytic activities of RuX_(2)@CNFs samples were investigated and compared in a fair and direct *** electrochemical measurements coupled with density functional theory calculations were carried out to probe their intrinsic HER catalytic activities,resulting in the catalytic activity order of RuS_(2)@CNFs>RuSe_(2)@CNFs>RuTe_(2)@CNFs in acidic media and that of RuS_(2)@CNFs>RuTe_(2)@CNFs>RuSe_(2)@CNFs in alkaline *** superior catalytic performance of RuS_(2)@CNFs mainly stems from the relative lower HER energy barriers and thereby the higher intrinsic catalytic activity of RuS_(2)(111),leading to ultralow overpotentials of 44 and 9 mV at 10 mA·cm^(-2) in acidic and alkaline media,***_(2)(111)is endowed with the more optimized Gibbs free energy of hydrogen adsorption(ΔGH*)than RuTe_(2)(111),but RuTe_(2)(111)shows enhanced catalytic property for H_(2)O dissociation and OH-desorption than RuSe_(2)(111),therefore,resulting in the altered catalytic activity sequences for RuSe_(2) and RuTe_(2) in acidic and alkaline media.

Bismaleimides/SiO nanocomposites(BMI/SiO) was prepared readily by in situ polymerization method where RNS-E(nano-SiO with surface epoxy group of carbon chain)and RNS-D(nano-SiO with a double bond of carbon chain) were used as the filler. The characteristics of namocomposites were studied by means of Shore hardness tester(D),TGA, FTIR, and other ***, the effects of nano-SiO on the thermal stability performance, hardness of bismaleimides,and interfacial strength between nano-SiO and bismaleimides were researched, and studying theirs *** results showed that the hardness of as-prepared BMI/SiO nanocomposites gradually enhanced with increasing the addition content of *** hardness of nanocomposites was 91HC when the RNS-E content was 5%;the hardness of nanocomposite with the content of 3% RNS-D was 91HC,as increased 65% in comparison with the hardness of BMI resins. This indicated that nano-SiO with surface active groups can significantly improve the hardness of bisimaleimides, and the action effect of RNS-D was better than *** thermal stability analysis showed that the decomposition temperature of nanocomposites of presented downtrend with the increase of nano-SiO, however, which were higher than 439 ° C of BMI resins. The thermal decomposition temperature of nanocomposites reached to 453 °C when the additon amount of RNS-E was 1%, as increased 14 °C in comparison with pure bismaleimides. And the thermal decomposition temperature of nanocomposites with the content of1% RNS-D was 457 °C, as compared with bismaleimides, it increased 18 °C. This showed that the thermal stability performance of BMI resins was improved because of adding to nano-SiO and the action effect of RNS-D better than RNS-E. The surface active groups of nano-SiO as the "bridging point" of nano-SiO chemically binds to bismaleimides, formed the "micro network" structure with taking nano-SiO as the core, through the interfacial effect of BMI/SiO nanocomposites w
