In situ growth of M-{001}TiO2/Ti photoelectrodes: synergetic dominant {001} facets and ratio-optimal surface junctions for the effective oxidation of environmental pollutants.

We report a novel {001}TiO2/Ti photoelectrode by directly constructing "mirror-like" TiO2 microspheres on a Ti foil substrate (M-{001}TiO2/Ti). It presents highly enhanced PEC oxidation capability of DMP wastewater, which is mainly attributed to the significant synergetic effects of high exposure of {001} facets and equivalent {001}/{101} facet junctions.

Recent progress on carbon nanomaterials for the electrochemical detection and removal of environmental pollutants.

Rapid global industrialization and explosive population growth have resulted in an increase in the discharge of harmful and toxic compounds. These toxic inorganic gases, volatile organic compounds, heavy metals, personal care products, endocrine-disrupting chemicals, dyes, and pharmaceuticals are destroying the balance in the Earth and increasing environmental toxicity at an alarming rate. Thus, their detection, adsorption and removal are of great significance. Various carbon nanomaterials including carbon nanotubes, graphene, mesoporous carbon, carbon dots, and boron-doped diamond have been extensively utilized and further proven to be ideal candidates for resolving environmental problems, emerging as adsorbents, electrochemical sensors and electrodes. Herein, we review the recent advances, progress and achievements in the design and properties of carbon nanomaterials and their applications for the electrochemical detection and removal of environmental pollutants.
