A fully enclosed hybrid electromagnetic–triboelectric nanogenerator has been designed to scavenge vibrational energy, thus solving the power source issues of some environmental sensors. Using a 200 μF capacitor, a temperature–humidity sensor can be sustainably powered without an external power source, by harvesting the vibrational energy produced by human hands.

A facile route was developed for the direct synthesis of CoSe2 nanoparticles on carbon fiber paper using a metal–organic framework as the precursor. The obtained electrode can serve as both the anode and cathode for efficient overall water splitting because of the bifunctional catalytic activity of CoSe2 nanoparticles in the hydrogen and oxygen evolution reactions.

Ternary NiCoP nanosheet arrays with ultrahigh electrocatalyticac tivity for overall water splitting and an extremely small potential(~1.77 V) for driving a current density of 50 mA/cm2 were prepared on Ni foam via a solvothermal synthesis followed by phosphorization.

Vertical α-FeOOH nanowires were successfully grown on the surface of carbon fiber paper via a simple hydrothermal reaction at low temperature. Owing to the highly oriented channels for fast charge transfer, the excellent electrical contact between the electrocatalyst and the current collector, and the good mechanical stability and reproducibility, this free-standing electrode with the portability in the geometric tailor and easy device fabrication serves as an efficient electrocatalyst for the reduction and sensitive detection of H2O2.

In the present work, a novel strategy using a thermally removable template was developed to synthesize hierarchically porous N-doped carbon nanofibers (HP-NCNFs) by employing a simple electrospinning technology coupled with subsequent pyrolysis. The obtained HP-NCNFs exhibited greatly enhanced catalytic performance and improved kinetics for the oxygen reduction reaction (ORR) in alkaline media.

Ultrathin Co(Ni)-doped MoS2 nanosheets (co-catalyst promoter)intimately grown on semiconductor CdS nanorods (light absorber)exhibited very high photocatalytic activity (quantum yield = 17.3%)and stability toward H2 evolution in the photoreduction of water.Theoretical calculations revealed that Ni doping can increase the number of uncoordinated atoms at the edge sites of MoS2 nanosheets to promote electron transfer across the CdS/MoS2 interfaces and hydrogen reduction, leading to an efficient H2 evolution reaction.

Raman-active molecules were embedded inside Au@Ag nanocuboids with finely tunable geometrical and optical properties.The surface-enhanced Raman scattering (SERS) of the embedded molecules showed an enhancement factor (EF) that was about an order of magnitude higher than that observed for the molecules adsorbed on the nanoparticle surface.
