Subnanometer materials, as an ideal platform for constructing strongly coupled interfaces at the atomic/cluster scale, are at the core of advancing efficient energy conversion technologies due to their ultimate atomic utilization efficiency, quantum confinement effects, and high specific surface area. The strongly coupled sub-nano interfacial structures developed based on such materials can simultaneously enhance the activity, selectivity, and durability of catalysts, holding the potential to overcome the limitations of traditional nanocatalysts in terms of atomic utilization and catalytic performance. However, the controllable synthesis of these materials remains challenging, constrained by the heavy reliance of traditional solvothermal methods on solvents, their high environmental footprint, and slow thermodynamic processes, making it difficult to capture metastable subnanometer structures. To address the controllable preparation of these materials, solvent-free microwave synthesis has emerged. This technique leverages the selective absorption of microwave energy by polar functional groups to generate transient high temperatures and ultrafast kinetics under solvent-free conditions, bypassing traditional thermodynamic limitations and providing a novel pathway for the precise synthesis of metastable subnanometer structures. This article systematically elaborates on the synthesis principles, research progress, and application prospects of such materials, aiming to provide theoretical support for the further development and industrialization of high-performance subnano catalytic materials.

The current research aims to improve the generation of bio-char with elevated higher heating values (HHVs) by utilizing magnesium oxide-zeolite-based catalysts across various temperature conditions. The exploration of biomass catalytic pyrolysis has intensified in the pursuit of sustainable energy solutions. Catalytic pyrolysis offers a technique to convert abundant and renewable biomass resources into valuable biofuels and bio-char, thereby improving energy security and reducing dependence on fossil fuels. The use of suitable catalysts in biomass catalytic pyrolysis is crucial for enhancing the yield of bio-char with higher calorific value. This investigation explores the impact of magnesium oxide-zeolite-based catalysts on the higher heating values of bio-char generated from coconut shells. The initial findings indicate a notable enhancement in the calorific value of bio-char. The HHV increased from 12.03 MJ/kg for untreated coconut shells to 20.06 MJ/kg with ZSM-5, ultimately reaching an impressive 38.11 MJ/kg with the MgO/ZSM-5 catalyst. The results demonstrate that the addition of magnesium oxide significantly improves the energy content of bio-char. Various combinations of magnesium oxide, such as MgO/ZSM-5, MgO/Y2O3/ZSM-5, and MgO/Mn3O4/ZSM-5, are evaluated for their effects on the pyrolysis process. The results demonstrate that the impregnation of metal oxides into zeolite catalysts enhances catalytic performance and facilitates the efficient conversion of coconut shells into high-energy bio-char. The findings highlight the promise of metal oxide-zeolite catalysts in improving bio-char quality and promoting the development of sustainable energy technologies.
