Article Synopsis
- - Plastic production has surged globally, leading to significant environmental concerns regarding plastic waste accumulation, making sustainable solutions essential.
- - Recyclable plastic waste can be transformed back into its basic building blocks (monomers) through a process called chemical recycling, which helps reduce reliance on fossil fuels and pollution.
- - The study focused on recycling PET plastic into its monomer BHET using a cost-effective and safe niobia-based catalyst, achieving a high conversion rate with efficient conditions.
Structure-sensitive epoxidation of dicyclopentadiene over TiO catalysts.
Chem Commun (Camb)
January 2023
Article Synopsis
- The research investigates how TiO catalysts facilitate the epoxidation of dicyclopentadiene (DCPD) using hydrogen peroxide, which is important for creating products in sectors like polymers and pharmaceuticals.
- It emphasizes the significance of controlling selectivity to achieve the desired epoxidation products, which is crucial for various applications.
- The study highlights that the surface crystalline phases of TiO are key factors in forming peroxo species and selectively epoxidizing different carbon-carbon double bonds in DCPD.
TiCT MXene Polymer Composites for Anticorrosion: An Overview and Perspective.
ACS Appl Mater Interfaces
September 2022
As the most studied two-dimensional (2D) material from the MXene family, TiCT has constantly gained interest from academia and industry. TiCT MXene has the highest electrical conductivity (up to 24,000 S cm) and one of the highest stiffness values with a Young's modulus of ∼ 334 GPa among water-dispersible conductive 2D materials. The negative surface charge of MXene helps to disperse it well in aqueous and other polar solvents.

Formate can be obtained from the (electro)catalytic reduction of CO, while oxalate can be further processed toward building blocks for modern plastics. In its 175 year history, multiple parameters for the FOCR have been suggested to be of importance.

- The authors developed a Sn SAC (Sn-NOC) with atomically dispersed SnN O sites on a nitrogen-rich carbon support, which exclusively produces CO instead of HCOOH.
- Their findings show that the specific atomic arrangement of SnN O lowers the activation energy for CO-related intermediates while increasing the energy barrier for HCOOH production, thus improving selectivity in CO conversion.
