Hierarchical hollow TiO2/In2S3 heterojunction photocatalyst decorated with spatially separated dual co-catalysts for enhanced photocatalytic H2 evolution

“…32-0456), respectively. 40–42 For the Pt/TiO 2 sample, in addition to the peaks from TiO 2 , a peak belonging to the cubic phase of Pt can be observed. For Pt/TO/IS and Pt/TO/IS/PdS nanocomposites, only the peaks attributed to TiO 2 and β-In 2 S 3 phases can be observed.…”

A Full-Spectrum ZnS Photocatalyst with Gradient Distribution of Atomic Copper Dopants and Concomitant Sulfur Vacancies for Highly Efficient Hydrogen Evolution

“…1 The efficiency is thwarted primarily by limited photoabsorption, ineffective charge separation, and slow H 2 evolution kinetics of semiconductor photocatalysts. 2 Particularly, infrared light that accounts for more than 45% of solar light energy, has been historically overlooked due to its relatively low photon energy, but it is crucial for solar utilization ability of photocatalysis. 3 Defect engineering has garnered significant attention as a powerful approach to overcome the above-mentioned restrictions and achieve high photocatalytic activity.…”

“…Photocatalytic hydrogen evolution from water splitting holds immense potential in addressing the global energy crisis, but its efficiency still falls short of meeting the essential criteria for practical applications . The efficiency is thwarted primarily by limited photoabsorption, ineffective charge separation, and slow H 2 evolution kinetics of semiconductor photocatalysts . Particularly, infrared light that accounts for more than 45% of solar light energy, has been historically overlooked due to its relatively low photon energy, but it is crucial for solar utilization ability of photocatalysis .…”

Green-route manufacturing towards future industrialization of metal halide perovskite nanocrystals

“…Perovskite NCs (PeNCs) with a range of merits, such as high light absorption coefficient, high defect tolerance, high colour purity, high brightness, and facile fabrication, have exhibited promising applications in LEDs (light-emitting diodes). 11–13 With the unique property of the multiple exciton generation (MEG) effect, 14 PeNCs have been extensively investigated in solar cells. 15–17 Up to now, the external quantum efficiency (EQE) of PeNC LEDs for red, green, and blue emissions have reached ∼29%, 18 ∼22%, 19 and ∼12%, 20 respectively, and the EQE of PeNC-based solar cells has been up to 17.4%.…”
