Heterojunction catalysts are attracting attention in the field of photocatalytic hydrogen generation for their effective light utilization and charge separation personalities. In this work, we report a simple low-cost two-step solvothermal method synthesizing Cu2O/TiO2 heterojunction with an octahedral morphology mean particle size about 30 nm. It is found that introduction Cu2O astonishingly enhances performance TiO2. Under condition methanol acting as sacrificial agent, 0.19% Cu species...
Abstract Sesquioxides such as Y 2 O 3 and Sc are important optical materials, but the fabrication of their transparent ceramics remains a challenge due to ultra-high melting point over 2400 ° C. In this work, series (Y 1− x ) were successfully fabricated by simple vacuum sintering process without any additives, effect scandium (Sc) content ( on crystal structure optical/thermal/mechanical properties was evaluated. form complete solid solution with cubic bixbyite structure. The formation...
Nanoscale metal borides, with exceptional physicochemical properties, have been attracted widespread attention. However, traditional synthesis methods of borides often lead to surface coking and large particle sizes. Herein, we employed a flash Joule heating (FJH) technique enable the ultrafast boride nanomaterials. The synthesized materials encompass wide range diverse categories, including alkaline‐earth (CaB6), transition (TiB2, VB2, CrB2, MoB, MoB2, MnB2, MnB4, FeB, CoB, NiB),...
Pristine fullerene C60 is an excellent electron transport material for state-of-the-art inverted structure perovskite solar cells (PSCs), but its low solubility leaves thermal evaporation as the only method depositing it into a high-quality layer (ETL). To address this problem, we herein introduce highly soluble bowl-shaped additive, corannulene, to assist in -assembly smooth and compact film through favorable bowl-ball interaction. Our results show that not corannulene can dramatically...
Nanoparticles (NPs) decorated ZnO/TiO2 core/shell nanorod arrays were fabricated on transparent conductive glass substrates by sequential plasma deposition and post-annealing processes for dye-sensitized solar cells (DSSCs) applications.

An efficient synthesis of 6H-isoindolo[2,1-a]indol-6-ones through rhodium-catalyzed NH-indole-directed C-H carbonylation 2-arylindoles with carbon monoxide has been developed. Preliminary mechanistic studies revealed that this reaction proceeds via N-H bond cleavage and subsequent cleavage. Reaction monitoring ESI-MS was used to support the formation five-membered rhodacycle species in catalytic cycle.
Large-scale pure titanate nanotubes were synthesized through the hydrothermal reaction between TiO2 powders and concentrated NaOH under an unexpected high temperature of 240 °C, while it was generally claimed that is impossible to form at temperatures higher than 180 °C. The nanotube found be inevitable intermediate product, which finally transformed into a nanowire upon increasing treatment duration. It proven successive appearance nanosheets, nanotubes, nanowires are three unavoidable...
