Abstract
In the modern era of rapid scientific and technological advancement, the preservation of the environment and natural resources has become increasingly important. In this context, there is growing interest in environmentally friendly, renewable, and highly efficient materials. MXene and nanocellulose are two promising nanomaterials that have attracted considerable scientific attention over the past decade. Their unique structural, chemical, and physical properties, as well as their multifunctionality, make them applicable across a wide range of fields.MXene is a two-dimensional material derived from the selective etching of MAX phases. Due to its high conductivity, hydrophilicity, thermal and chemical stability, and tunability, it is widely studied in water purification, energy storage, electronics, sensors, and biomedical applications. Nanocellulose, a bio-based, biodegradable material obtained from plant cellulose, offers high mechanical strength, a large surface area, and chemical stability, making it a valuable material in medicine, food packaging, and nanocomposites.This article provides a detailed review of synthesis methods for these materials (e.g., HF or LiF/HCl etching for MXene, and acid hydrolysis, mechanical, and enzymatic treatment for nanocellulose), along with their morphological and structural characteristics. It also explores their individual and combined application potentials, particularly in nanocomposites and membrane systems. The analysis shows that due to their compatibility and high functionality, these materials may serve as essential components in future green technologies aimed at solving ecological and technogenic challenges.
