Visible-light-induced NiCo2O4@Co3O4 core/shell heterojunction photocatalysts for efficient removal of organic dyes

Recovery of Germanium via H2SO4/MnO2 Leaching–NaAc Leaching/Na2CO3 Precipitation–Tri(octyl-decyl) Amine Stepwise Solvent Extraction

“…N235, which is dissolved or mechanically stirred into the aqueous phase, has a negative influence on zinc electrowinning, as it requires purging for use in subsequent procedures. Similarly, NaOH that was mechanically mixed in the organic phase during the stripping step should be removed; if not, a significant amount of Na will be included in the zinc system.…”

Engineering the nanostructures of solution proceed In2Se x S3−x films with enhanced near-infrared absorption for photoelectrochemical water splitting

“…Actually, the heterogeneous hydrogen evolution reaction is quite complex with multiple reaction steps, including the thermodynamic adsorptions, electron transfer or photons absorption, finally an excellent catalyst should catalyze a pair of protons and electrons to H 2 molecule at low over potentials and high reaction rates [4][5][6][7][8][9][10][11]. For the electrochemical catalysts, great efforts have been made for the edge-rich nanostructures, efficient electron transfer interfaces, and the selection of good intrinsic catalysts with strong thermodynamic adsorptions [11][12][13][14][15][16][17]. However, high-performance PEC water splitting is far more difficult because of the requirement of the Z-scheme junction device structures, the matching absorption with sunlight spectrum, carriers' generation and separation [15,[18][19][20][21][22].…”

Therefore, it is still necessary to search the new materials system and devices structures for finding robust and efficient PEC catalysts to solve the above challenges [23,24].…”

Natural Diatomite Supported Zirconium-Doped TiO2 with Tailoring Band Structure for Enhanced Visible-Light Photocatalytic Properties

“…At present, the removal methods of antibiotics mainly include physical methods (adsorption [9,10], membrane filtration [11], etc. ), chemical methods (ozonation [12], electrochemical oxidation [13], photocatalysis [14][15][16], etc. ), biological methods (biosurfactant treatment [17], activated sludge degradation [18,19], etc.).…”
