Heterojunction Engineering of Multinary Metal Sulfide‐Based Photocatalysts for Efficient Photocatalytic Hydrogen Evolution

Advanced Materials, Год журнала: 2023, Номер 36(11)

Опубликована: Дек. 2, 2023

Photocatalytic hydrogen evolution (PHE) via water splitting using semiconductor photocatalysts is an effective path to solve the current energy crisis and environmental pollution. Heterojunction photocatalysts, containing two or more semiconductors, exhibit better PHE rates than those with only one owing altered band alignment at interface stronger driving force for charge separation. Traditional binary metal sulfide (BMS)-based heterojunction such as CdS, MoS

Enhanced CO₂ Photoreduction through Spontaneous Charge Separation in End‐Capping Assembly of Heterostructured Covalent‐Organic Frameworks

Angewandte Chemie International Edition, Год журнала: 2022, Номер 61(50)

Опубликована: Окт. 13, 2022

It is well known that charge separation crucial for efficient photocatalytic solar conversion. Although some covalent-organic frameworks (COFs) exhibit visible-light harvest, the large exciton binding energies reduce their efficiencies. Herein, we developed a novel method to post-treat olefin-linked COFs with end-capping polycyclic aromatic hydrocarbons (PAHs) spontaneous separation. Interestingly, type-II heterostructure constructed in our perylene-modified which displays drastically enhanced performance CO2 reduction, an efficiency of 8-fold higher than unmodified COF. A combination electrochemical, steady-state, and time-resolved spectroscopic measurements indicates such should be attributed photoinduced heterostructure. These results illustrate feasibility engineering charge-separation properties crystalline porous at molecular level artificial photosynthesis.

Abstract Piezocatalytic pure water splitting for H 2 evolution carries the virtues of efficacious utilization mechanical energy, easy operation, and high value‐added products, while lacking desirable piezoelectrics chemical energy production. Here, two polar layered bismuth‐rich oxyhalides Bi 4 O 5 X (XBr, I) thin nanosheets (≈4 nm) are first exploited as efficient piezocatalysts to be capable dissociating water. The unique asymmetrical structures composed interleaved [Bi ] 2+ layer double − ions slabs along [1 0 1_] orientation cause large intrinsic dipole moment, excellent piezoelectricity deformation. Without any cocatalyst sacrificial agent, Br I display remarkable piezocatalytic production rate 1149.0 764.5 µmol g −1 h , respectively, standing among best piezocatalysts, accompanied by hydroxyl radicals (·OH) oxidative products. smaller radius higher electronegativity than a more strongly crystal structure in contributing activity compared . This study broadens scope piezoelectric materials applied sustainable catalysis efficiently converting illustrates importance configuration composition fabricating systems.
