A C@TiO₂ yolk–shell heterostructure for synchronous photothermal–photocatalytic degradation of organic pollutants

Abstract

A novel approach integrates the hetero-interfacial charge carrier management, the photothermal excitation of the carbon sphere core and the injection of hot electrons into the TiO2 shells, consequently enhancing the visible light driven catalysis.

Polypyrrole–polyaniline copolymer coated green rice husk ash as an effective adsorbent for the removal of hexavalent chromium from contaminated water

“…6,15 Therefore, several studies have been performed for the removal of Cr(VI) using various adsorbent such as silica, activated carbon, clay, metal oxides, bauxite, biomaterials, zeolites, layered double hydroxide, etc. 5, [16][17][18] Besides, hybrid materials, such as titanium cross-linked chitosan, 19 Magnetic Carbon Nanoadsorbent, 20 C@TiO 2 , 21 etc. have also been employed as adsorbents in the separation of pollutant from contaminated water.…”

Highly effective Fe–N–C electrocatalysts toward oxygen reduction reaction originated from 2,6-diaminopyridine

“…PDAP can be mainly divided into three stages. The rst starts at 40 °C and reaches a plateau at about 180 °C, with an associated mass loss of 19%, which can be assigned to the volatilization of absorbed water [35,36]. The second step, from 180 to 420 °C, shows a mass loss of 20%, which might be related to the cleavage of C-N bond of pyridine C-NH 2 group in PDAP as well as some polymers with low molecular weight.…”

Photothermal Chemistry Based on Solar Energy: From Synergistic Effects to Practical Applications

“…[ 21 ] Some specific nanoscale or mesoscale structures, such as nanowires, hollow spheres, core–shell structures, flower‐like structures, photonic crystals, and so on, can enhance light absorption at a broad spectral range, thereby enhancing the heat generation.
