Influence of pyrolysis temperature on characteristics and environmental risk of heavy metals in pyrolyzed biochar made from hydrothermally treated sewage sludge.
A novel approach was used to prepare sewage sludge (SS)-derived biochar via coupling of hydrothermal pretreatment with pyrolysis (HTP) process at 300-700 °C. The influence of the pyrolysisExpand

Effect of pyrolysis temperature on characteristics, chemical speciation and risk evaluation of heavy metals in biochar derived from textile dyeing sludge.
Textile dyeing sludge (TDS) was pyrolyzed at temperature ranging from 300 to 700 °C to investigate characteristics and to evaluate the risk of heavy metals (Zn, Cu, Cr, Ni, Cd, and Mn) in biocharExpand

Catalytic upgrading of coal pyrolysis tar over char-based catalysts
Catalytic upgrading of coal pyrolysis tar was investigated in a dual-stage reactor over char and metal-impregnated char (Co-char, Ni-char, Cu-char, Zn-char). The catalytic upgrading caused the lowerExpand

Dielectric relaxation studies of Bi-doping effects on the oxygen-ion diffusion in La2−xBixMo2O9 oxide-ion conductors
Two dielectric relaxation peaks associated with oxygen-ion diffusion in the oxide-ion conductors La2−xBixMo2O9 (x=0.05, 0.1, and 0.15) have been studied. It is found that the activation energies ofExpand

Direct synthesis of parallel doped N-MoP/N-CNT as highly active hydrogen evolution reaction catalyst
Doped phosphide is promising in earth-abundant element based catalysts for hydrogen evolution reaction (HER). Here we employ ammonium hypophosphite (NH4H2PO2) to synthesize a novel parallel dopedExpand

Mechanistic insight into the selective olefin-directed oxidative carbocyclization and borylation by a palladium catalyst: a theoretical study
A mechanistic study of palladium-catalyzed oxidative carbocyclization and borylation of allenes was carried out by using density functional theory (DFT) calculations. A subtle change in the reactionExpand
