an efficient and chemoselective procedure for the preparation of 1, 1-diacatates (acylals) from various aldehydes with acetic anhydride in the presence of brønsted acidic ionic liquid [msei]cl as a reusable catalytic system under solvent-free condition at room temperature and short periods of times with excellent yields will be described. the catalyst was easily separated in simple work-up and ...

zns  nanoparticles  were  synthesized  via  a  simple  surfactant  free microwave  route.  in  this  synthesis, thioacetamide  was  used  as sulfur  source.  the effects  of different  parameters  such  as  type of zinc precursor,  time  and  power  of  irradiation  on  the  morphology and  particle  size  of  the  products  have been  investigated.  the nanostructures  were  characterized  by ...

Photo(electro)catalysis (PEC) is a promising strategy to conduct attractive solar-driven reactions such as CO2 reduction form added-value products, H2 production, and organic substrates oxidation, taking advantage of the spatial separation photocarriers generated in semiconductor-based electrodes. Halide perovskite nanocrystals (PNCs) are attracting increasing attention due their tunable optica...

Lanthanum nitride (LaN) has attracted research interest in catalysis due to its ability activate the triple bonds of N$_2$ molecules, enabling efficient and cost-effective synthesis ammonia from gas. While exciting progress been made use LaN functional applications, electronic character (metallic, semi-metallic, or semiconducting) magnitude band gap have so far not conclusively determined. Here...

The photocatalytic process employing nanostructured semiconductor materials has attracted great attention in energy production, CO2 reduction, and water/air purification for decades. Recently, applying heterogeneous photocatalyst the synthesis of valuable chemicals is gradually emerging considered as a promising conversion cheap resources (i.e., biomass derivatives, polyols, aromatic hydrocarbo...

Abstract Composites‐based photocatalysis relies on the interfacial electron transfer between metallic cocatalyst and photosensitizer (the semiconductor) to realize spatial separation of charge carriers. Herein, an ingenious heterojunction Co‐CN single atom catalysts (SACs) g‐C 3 N 4 is constructed for heterogeneous photo‐Fenton‐like reactions. Driven by built‐in electric field across heterojunc...

I-III-VI2 semiconductor nanocrystals have been explored in countless optoelectronics and green energy applications. While indium-based compounds are arguably the best-known variants of these semiconductors widely studied for their photophysical properties, other emerging as serious competitors. This review focuses on current state art recent progress made research technology one most promising ...
