Summary: The assembly pattern of micelles plays a crucial role in determining the architectures of carbon materials prepared via soft-templating method. In this study, a kinetics-controlled strategy is developed to fabricate ordered mesoporous carbon (OMC) single crystals from liquefied wood by regulating the polymerization rate of carbon precursors using melamine. The addition of melamine slows down the reaction kinetics, allowing composite micelles to orderly aggregate and form OMC single crystals with high specific surface areas, uniform mesopore size, and ordered Im3m mesostructure. These OMC single crystals show excellent catalytic performance for the reduction of 4-nitrophenol when coupled with Ag nanoparticles.

Summary: Due to their unique properties, such as high surface area, enhanced catalytic properties, and biological applications, there is growing interest in porous materials. While solvent-based approaches have been used to synthesize porous materials, the large volume of solvents, their toxicity, and time-consuming synthesis make this process less effective in terms of green chemistry principles. Mechanochemical synthesis provides an effective and eco-friendly alternative, using ball milling to efficiently mix reactants with minimal or no solvents, resulting in smaller nanoparticles and larger surface area, which is highly beneficial for antimicrobial applications.
