Solution-based synthesis of ZnO/carbon nanostructures by chemical coupling for high performance gas sensors

ZnO quantum dots-graphene composites: Formation mechanism and enhanced photocatalytic activity for degradation of methyl orange dye

“…As regard to only being active in the UV region of the solar light, and thus absorbing only 5% of the sunlight energy, extending of the band gap of ZnO into the visible region, and hence improving of its photocatalytic efficiency is of great importance [9,10]. One of the suggested methods for this purpose is decorating of ZnO nanoparticles (NPs) on a substrate with high surface area such as zeolite, nanoclay or carbon-based materials [11][12][13]. The aforementioned carbon-based materials are divided into two categories:1-Conventional, including graphite, carbon black, and activated carbon which have been studied extensively, and 2-New family comprising carbon nanotube (CNT), fullerenes, and most recently graphene.…”

Microwave-assisted synthesis of carbon-supported carbides catalysts for hydrous hydrazine decomposition

“…Previously, similar carbon -ceramic nanoparticles composites with unusual catalytic and gas-sensing properties were also reported [31,32]. Indeed, carbon is known as an excellent absorber of microwave irradiation [33].…”

Streptavidin and gold nanoparticles-based dual signal amplification for sensitive magnetoelastic sensing of mercury using a specific aptamer probe

“…These sensors have some noteworthy advantages of being low cost, remote query and high sensitivity [15][16][17]. Nanomaterials such as graphene oxide (GO) have attracted much interest recently [18][19][20][21][22]. Particularly, GO is able to serve as a "nanoscaffold" for ssDNA by π-stacking interactions [23].…”
