In Situ Prepared Solar Light-Driven Flexible Actuated Carbon Cloth-Based Nanorod Photocatalyst for Selective Radical-Radical Coupling to Vinyl Sulfides

Highly Efficient Self-Assembled Activated Carbon Cloth-Templated Photocatalyst for NADH Regeneration and Photocatalytic Reduction of 4-Nitro Benzyl Alcohol

This manuscript emphasizes how structural assembling can facilitate the generation of solar chemicals and the synthesis of fine chemicals under solar light, which is a challenging task via a photocatalytic pathway. Solar energy utilization for pollution prevention through the reduction of organic chemicals is one of the most challenging tasks. In this field, a metal-based photocatalyst is an optional technique but has some drawbacks, such as low efficiency, a toxic nature, poor yield of photocatalytic products, and it is expensive. A metal-free activated carbon cloth (ACC)–templated photocatalyst is an alternative path to minimize these drawbacks. Herein, we design the synthesis and development of a metal-free self-assembled eriochrome cyanine R (EC-R) based ACC photocatalyst (EC-R@ACC), which has a higher molar extinction coefficient and an appropriate optical band gap in the visible region. The EC-R@ACC photocatalyst functions in a highly effective manner for the photocatalytic reduction of 4-nitro benzyl alcohol (4-NBA) into 4-amino benzyl alcohol (4-ABA) with a yield of 96% in 12 h. The synthesized EC-R@ACC photocatalyst also regenerates reduced forms of nicotinamide adenine dinucleotide (NADH) cofactor with a yield of 76.9% in 2 h. The calculated turnover number (TON) of the EC-R@ACC photocatalyst for the reduction of 4-nitrobenzyl alcohol is 1.769 × 1019 molecules. The present research sets a new benchmark example in the area of organic transformation and artificial photocatalysis.

In-Situ Prepared NRCPFs as Highly Active Photo-platforms for In-Situ Bond Formation Between Aryldiazonium Salts and Heteroarenes

Covalent perylene frameworks (CPFs) with melamine linkages have newly received risinginterest for a variety of applications because of nitrogen rich content and high stability. Herein we account a new simple strategy to in-situ attain nitrogen rich covalent peryleneframeworks (NRCPFs) as highly active photo-platforms for in-situ bond formation betweenaryldiazonium salts and heteroarenes (C-H bond arylation) through the controlled photoredoxroute.

Construction of LZU1@WO3 heterojunction photocatalysts: enhanced photocatalytic performance and mechanism insight

Our well-designed nano-WO3@LZU1 composite photocatalysts were fully characterized. Under simulated sunlight, the hybrid materials showed much higher photocatalytic activity for BBR degradation and MB degradation than WO3 or LZU1, and improved hydrogen production capacity.
