All-inorganic CsPbX3 (X = Cl, Br or I) perovskite nanocrystals have attracted extensive interest recently due to their exceptional optoelectronic properties. In an effort improve the charge separation and transfer following efficient exciton generation in such nanocrystals, novel functional nanocomposites were synthesized by situ growth of CsPbBr3 on two-dimensional MXene nanosheets. Efficient excited state occurs between NCs nanosheets, as indicated significant photoluminescence (PL)...
Dual-comb spectroscopy holds the promise as real-time, high-resolution tools. However, in its conventional schemes, stringent requirement on coherence between two lasers requires sophisticated control systems. By replacing electronics with an all-optical dual-comb lasing scheme, a simplified scheme is demonstrated using one dual-wavelength, passively mode-locked fiber laser. Pulses intracavity-dispersion-determined repetition-frequency difference are shown to have good mutual and stability....
Photoelectrochemical (PEC) water splitting represents a promising route to convert solar energy into clean hydrogen. Constructing tandem cells has emerged as feasible approach and attracted tremendous attention for self-biased splitting, especially using low-cost stable metal oxides. Herein, state-of-the-art review of oxide-based PEC/photovoltaic (PV) PEC is comprehensively presented, with focus on crucial issues designing efficient devices from the aspects photoanodes, photocathodes,...
Solar-driven CO2 conversion to chemical fuels in an aqueous solution is restricted not only by photocatalysts but also mass transfer. Here, a regulatable three-phase interface on porous fixed-bed constructed for efficient C–C coupling photocatalytic reduction. The results show that ∼90% selectivity towards C2+ products obtained Cu/Cd0.5Zn0.5S photocatalyst, with yield of 6.54 μmol/h (an irradiation area 0.785 cm2), while 0.94 19.625 cm2) achieved commonly used suspension reactor. We find...
Photocatalytic CO2 conversion to fuels is a promising strategy for achieving global carbon neutrality. However, infrared light, which accounts ∼50% of the full sunlight spectrum, has not yet been effectively utilized via photocatalysis. Here, we present an approach directly power photocatalytic reduction using near-infrared light. This light-responsive process occurs on in situ generated Co3O4/Cu2O photocatalyst with nanobranch structure. Photoassisted Kelvin probe force microscopy and...
Abstract Retrogressive thaw slumps (RTSs) have become a dominant geomorphic event in permafrost regions due to the modern climate change. However, roles of topographic, vegetation, and soil factors influencing spatial distribution recurrence RTSs remain not fully understood. Here, we identified formation 459 during 2008–2021 using satellite images central Qinghai‐Tibet Plateau (Northwest Beiluhe Basin, 239 km 2 ). We found that topographic environmental attributes exhibited strong...
Abstract Controlling the concentrations of H 2 O and CO at reaction interface is crucial for achieving efficient electrochemical reduction. However, precise control these variables during catalysis remains challenging, underlying mechanisms are not fully understood. Herein, guided by a multi-physics model, we demonstrate that tuning local O/CO achievable thin polymer coatings on catalyst surface. Beyond often-explored hydrophobicity, properties gas permeability water-uptake ability even more...
Indium-based oxides are promising electrocatalysts for producing formate via CO2 reduction reaction, in which *OCHO is considered the key intermediate. Here, we identified that *COOH pathway could be preferential to produce on In2O3 of In/In2O3 heterojunction due synergistic effect oxygen species and vacancy. Specifically, *CO2 were observed related production by situ Raman spectroscopy. The theoretical calculations further demonstrated energy barrier formation was decreased presence...
Core-shell structural CdS@SnO2 nanorods (NRs) were fabricated by synthesizing SnO2 nanoparticles with a solvent-assisted interfacial reaction and further anchoring them on the surface of CdS NRs under ultrasonic stirring. The morphology, composition, microstructures obtained samples characterized field-emission scanning electron microscopy, transmission X-ray diffraction, photoelectron spectroscopy, nitrogen adsorption-desorption. It was found that can be tightly anchored NRs, thickness...

A series of Bodipy dimers with orthogonal conformation were prepared. The photophysical properties studied steady-state and time-resolved transient spectroscopies. We found the triplet-state quantum yield is highly dependent on solvent polarity in orthogonally linked symmetric dimers, intersystem crossing (ISC) efficient solvents moderate polarity. photoinduced symmetry-breaking charge transfer (SBCT) polar was confirmed by femtosecond absorption spectroscopy, separation (CS) kinetics order...
Abstract Coal consumption leads to over 15 billion tons of global CO 2 emissions annually, which will continue at a considerable intensity in the foreseeable future. To remove huge amount , practically feasible way direct carbon mitigation, instead capturing that from dilute tail gases, should be developed; as intended, we developed two innovative supporting technologies, status, strengths, applications, and perspective are discussed this paper. One is supercritical water gasification-based...
