Abstract The nanosheet stacking phenomenon in graphene thin films significantly deteriorates their gas-sensing performance. This nanosheet stacking issue should be solved and reduced to enhance the gas detection sensitivity. In this study, we report

The poor sensing performance of reduced graphene oxide (RGO) and difficult recovery of RGO-based gas sensors have long been the challenging issues to overcome. In this work, the characteristic properties of cerium oxide (CeO2), including strong absor

Hierarchical Cu2O/CuO mesocrystals have been fabricated by a one-step, controllable and low-power method. A novel “Etch-Oriented Self-Assembly” growth mechanism is proposed to describe the formation of hierarchical Cu2O/CuO mesocrystals. In an al

Generally, due to structural disorders in multi-walled carbon nanotubes (MWCNTs) synthesized by chemical vapor deposition (CVD), most of their properties are much below the expected values. A novel technique has been developed in this investigation f
