The controllable morphology and composition of catalysts are crucial to improving the electrocatalytic activity of oxygen evolution reaction(OER).herein,we construct a bimetallic heterostructure by sulfidation and hydrothermal methods,and the layered Res_(2)is vertically aligned on Prussian blue-derived hollow Co_(9)s_(8)nanocubes(Co_(9)s_(8)@Res_(2)).The core-shell structure of Co_(9)s_(8)@Res_(2)can effectively prevent the restacking of layered Res_(2),expose the abundant surface area and improve the utilization of electrocatalytic sites,resulting in fast electrolyte diffusion and charge transfer during *** to the synergistic effect of the core-shell morphology and the formed bimetallic heterostructure,Co_(9)s_(8)@Res_(2)exhibits excellent catalytic OER *** 10 mA/cm^(2),only 288 mV of overpotential is required with the Tafel slope of 73.3 mV/dec for Co_(9)s_(8)@Res_(2),which are both lower than that of Co_(9)s_(8)and Res_(2).Meanwhile,Co_(9)s_(8)@Res_(2)exhibits high catalytic stability and low charge transfer resistance and the boosted active sites are confirmed by density functional *** work provides a rational design of the OER catalysts by constructing the bimetallic heterostructure.

Pre-polymerized vinyl trimethoxy silane(PVTMs)@MWCNT nano-aerogel system was constructed via radical polymerization,sol-gel transition and supercritical CO_(2)*** fabricated organic-inorganic hybrid PVTMs@MWCNT aerogel structure shows nano-pore size(30-40 nm),high specific surface area(559 m^(2)g^(−1)),high void fraction(91.7%)and enhanced mechanical property:(1)the nano-pore size is beneficial for efficiently blocking thermal conduction and thermal convection via Knudsen effect(beneficial for infrared(IR)stealth);(2)the heterogeneous interface was beneficial for IR reflection(beneficial for IR stealth)and MWCNT polarization loss(beneficial for electromagnetic wave(EMW)attenuation);(3)the high void fraction was beneficial for enhancing thermal insulation(beneficial for IR stealth)and EMW impedance match(beneficial for EMW attenuation).Guided by the above theoretical design strategy,PVTMs@MWCNT nano-aerogel shows superior EMW absorption property(cover all Ku-band)and thermal IR stealth property(ΔT reached 60.7℃).Followed by a facial combination of the above nano-aerogel with graphene film of high electrical conductivity,an extremely high electromagnetic interference shielding material(66.5 dB,2.06 mm thickness)with superior absorption performance of an average absorption-to-reflection(A/R)coefficient ratio of 25.4 and a low reflection bandwidth of 4.1 Ghz(A/R ratio more than 10)was experimentally obtained in this work.
