Multichromophoric Triad and g-C3N4 Composite as Efficient Heterogeneous Photocatalyst for Oxidative Amidation of Aldehydes.

In this work, we have synthesized a multichromophoric light-harvesting antenna, namely, triad, consisting of naphthalene monoimide (NMI) and perylene monoimide (PMI) chromophores. Triad was adsorbed onto polymeric graphitic carbon nitride (g-C3N4) to form triad/g-C3N4 composite, utilized as a photocatalyst for oxidative amidation reaction. This composite photocatalyst demonstrated enhanced photocatalytic activity for the conversion of a variety of aldehydes to amides, leading up to 82% product yield compared to only g-C3N4 or only triad as photocatalysts.

Naphthalene Monoanhydride and Perylene Composites for Efficient Photocatalytic Hydrogen Evolution and Metal-Free Heterogeneous Oxidative Amidation.

This study explores the synthesis of two visible light active organic chromophore-based composites using naphthalene monoanhydride () and 1,7-dibromoperylene monoanhydride diester (). These chromophores feature favorable optical and electronic properties and polyaromatic skeletons with anhydride functionalities that facilitate π-π interactions between the chromophore and polymeric carbon nitride () or covalent connections of chromophores with NH groups of . Accordingly, heterogeneous chromophore- composite photocatalysts namely, and were prepared by adopting calcination (c) and composites and were prepared by physical adsorption (a) methods.

Context-dependent agricultural intensification pathways to increase rice production in India.

Yield gap analysis is used to characterize the untapped production potential of cropping systems. With emerging large-n agronomic datasets and data science methods, pathways for narrowing yield gaps can be identified that provide actionable insights into where and how cropping systems can be sustainably intensified. Here we characterize the contributing factors to rice yield gaps across seven Indian states, with a case study region used to assess the power of intervention targeting.

A surface reconstruction route for increasingly improved photocatalytic HO production using SrBiTaOCl.

Photocatalytic hydrogen peroxide (HO) generation is attractive for the chemical industry and energy production. However, photocatalysts generally deteriorate significantly during use to limit their application. Here we present highly active SrBiTaOCl single-crystal nanoplates for conversion of O to HO using ambient air with a production rate of ∼3 mmol h g (maximum 17.

Tailoring the structural and electro-optical properties of avisible-light emitting BaZrO photocatalyst: integrating DFT and comprehensive experimental analysis.

In the present work, the synthesis of BaZrO nano-ceramics is explored through flash combustion utilizing glycine as a fuel. The resulting nanoparticles exhibit a cubic 3̄ space group and a spherical morphology with an average size of 45.31 nm.
