演講摘要：

The rapidly expanding personal electronics in communication, wearable electronics, medical devices, environmental monitoring have dramatically increasing in the past decade. The number of batteries in the waste stream increase with increasing the number of portable electronics used. It is very critical task to search a better solution to reduce the electronic waste especially on the dispose of batteries. Researchers are now working to find alternative energy such as solar cell, biofuels, thermoelectricity, and nanogenerators to provide the electricity for personal electronics. This work, we are the first to discover a high short-circuit current density of triboelectric nanogenerator using recycling rice husks as a source material. On the basis of our FTIR spectra, the nanoporous RHSiO2 fragents offers highly dense Si-O-Si, Si-OH, and OH stretching bonds compare to commercial SiO2 nanoparticles. The RHSiO2 film therefore exhibits strongly tendency to repel the electron because the H atoms have an extremely low electron affinity compared to the PTFE film. The highly positively charged surfaces of the nanoporous RHSiO2 film in five times higher than that of commercially non-porous SiO2 film based on our theoretical calculate results. Interestingly, the porous RHSiO2 film can offer a rapidly charging and discharging process due to its wide range of pore size distribution, leading to the peak short-circuit (Isc) current density of 5.7 mAm-2 was measured from the RHSiO2 triboelectric nanogenerator (RHSiO2 TENG).
