Synthesis of Ni2P/Ni12P5 composite for a highly efficient hydrogen production from formaldehyde solution
A series of nickel phosphide were synthesized by a simple solid phosphidation reaction and used as catalysts for H2 production from formaldehyde solution. It is found that by changing the molar ratio of Ni and P ...

Temperature evolution during the compaction of calcium silicate hydrate powders using a compression calorimeter
Amorphous calcium silicate hydrate (CSH) undergoes contact-hardening property, i.e. the powder can be hardened by compression. A compression calorimeter was designed to determine the temperature evolution during ...

Modification of TiO2 with sulfate and phosphate for enhanced eosin Y-sensitized hydrogen evolution under visible light illumination
TiO2 was modified with sulfate and phosphate (denoted as S/TiO2 and P/TiO2) through a simple sulfuric or phosphoric acid treatment. A strong coordination bond forms between sulfate or phosphate and Ti4+ of TiO2. ...

Preparation of SiO2-Pt-CdS composite photocatalyst and its photocatalytic activity for hydrogen evolution under visible light
CdS nanoparticles were prepared by the precipitation method. Pt was loaded on CdS by photodeposition. SiO2-Pt-CdS was synthesized via hydrolysis of tetraethylorthosilicate in the presence of Pt-CdS. The samples w...
