Special Issue Information

Dear Colleagues,

Catalysis is a cornerstone for the green transition, enhancing the efficiency of converting renewable resources like biomass, water, and CO2 into valuable fuels and chemicals. This efficiency is crucial for scaling up green technologies and making them economically viable. Catalysis also helps reduce greenhouse gas emissions by transforming CO2 into useful products, aiding climate change mitigation. By integrating renewable energy sources such as solar and wind, catalytic processes further decrease reliance on fossil fuels. Adhering to green chemistry principles, catalysis minimizes waste and energy consumption, aligning with a circular economy, and is thus indispensable for developing sustainable energy and fuel production methods.

This Special Issue is devoted to the most recent results focused on the design and application of new catalytic materials with enhanced performance and stability for fuel and chemical synthesis from renewable biomass feedstocks and CO₂. We encourage contributions that not only advance the scientific understanding of catalytic mechanisms but also demonstrate practical applications and potential for industrial implementation.

High-nickel ternary LiNi0.6Co0.2Mn0.2O2 (NCM622) is a promising cathode material for lithium-ion batteries due to its high discharge-specific capacity and energy density. However, problems of NCM622 materials, such as unstable surface structure, lithium–nickel co-segregation, and intergranular cracking, led to a decrease in the cycling performance of the material and an inability to fully utilize high specific capacity. Surface coating was the primary approach to address these problems. The effect of TiO2 coating prepared by the sol–gel method on the performance of LiNi0.6Co0.2Mn0.2O2 was studied, mainly including the morphology, cell structure, and electrochemical properties. LiNi0.6Co0.2Mn0.2O2 was coated by TiO2 with a thickness of about 5 nm. Compared with the pristine NCM622 electrode, the electrochemical performance of the TiO2-coated NCM622 electrodes is improved. Among all TiO2-coated NCM622, the NCM622 cathode with TiO2 coating content of 0.5% demonstrates the highest capacity retention of 89.3% and a discharge capacity of 163.9 mAh g−1, in contrast to 80.9% and145 mAh g−1 for the pristine NCM622 electrode, after 100 cycles at 0.3 C between 3 and 4.3 V. The cycle life of the 5 wt% TiO2-coated NCM622 electrode is significantly improved at a high cutoff voltage of 4.6 V. The significantly enhanced cycling performance of TiO2-coated NCM622 materials could be attributed to the TiO2 coating layer that could block the contact between the material surface and the electrolyte, reducing the interface side reaction and inhibiting the transition metal dissolution. At the same time, the coating layer maintained the stability of layered structures, thus reducing the polarization phenomenon of the electrode and alleviating the irreversible capacity loss in the cycle process.
