Highly efficient mobility, separation and charge transfer in black SnO-TiO structures with co-catalysts: the key step for the photocatalytic hydrogen evolution.

Oxygen vacancies and co-catalysts enhance photocatalytic hydrogen production by improving the charge carrier separation. Herein, the black SnO-TiO structure (BST) was synthesized for the first time by two consecutive methods. First, the sol-gel nucleation method allowed TiO to form on the SnO nanoparticles, creating a strong interaction and direct contact between them.

Degradation Behavior and Mechanical Integrity of a Mg-0.7Zn-0.6Ca (wt.%) Alloy: Effect of Grain Sizes and Crystallographic Texture.

The microstructural characteristics of biodegradable Mg alloys determine their performance and appropriateness for orthopedic fixation applications. In this work, the effect of the annealing treatment of a Mg-0.7Zn-0.

Synergistic photocatalytic effect of BiOBr-BiOI heterojunctions due to appropriate layer stacking.

The increasing interest in acquiring efficient visible-light active photocatalytic materials has led to the formation of heterojunctions with different combinations of semiconductors. Despite the fact that increasingly more complex structures are proposed, there are still many unclear factors affecting their performance and limiting their prompt implementation. In this work, we used the spray pyrolysis technique to deposit individual visible light-active BiOBr and BiOI films and formed the heterojunctions BiOBr-BiOI and BiOI-BiOBr to determine the effect of the stacking order of semiconductors.
