“…Therefore, cellulose is considered a neutral nanoreactor [53]. Hydrogels produced from pristine cellulose along with aerogels, films, powder samples, and fibers were successfully applied as scaffolds (carriers, matrices, sacrificing templates) for intercalation of transition zero-valent d-metals, such as cobalt, nickel, silver, gold, platinum, palladium, iron, copper, zinc or/and their oxides [51][52][53][54][55][56][57][58][59][60]. For example, it was shown that the hydrate cellulose film could be successfully used to obtain nickel nano-and microspecies located mainly on the surface or in the near-surface layer.…”

Metallogels are a class of materials produced by the complexation of polymer gels with metal ions that can form coordination bonds with the functional groups of the gel. Hydrogels with metal phases attract special attention due to the numerous possibilities for functionalization. Cellulose is preferable for the production of hydrogels from economic, ecological, physical, chemical, and biological points of view since it is inexpensive, renewable, versatile, non-toxic, reveals high mechanical and thermal stability, has a porous structure, an imposing number of reactive OH groups, and good biocompatibility. Due to the poor solubility of natural cellulose, the hydrogels are commonly produced from cellulose derivatives that require multiple chemical manipulations. However, there is a number of techniques of hydrogel preparation via dissolution and regeneration of non-derivatized cellulose of various origins. Thus, hydrogels can be produced from plant-derived cellulose, lignocellulose and cellulose wastes, including agricultural, food and paper wastes. The advantages and limitations of using solvents are discussed in this review with regard to the possibility of industrial scaling up. Metallogels are often formed on the basis of ready-made hydrogels, which is why the choice of an adequate solvent is important for obtaining desirable results. The methods of the preparation of cellulose metallogels with d-transition metals in the present state of the art are reviewed.

As the most abundant natural polymer, cellulose presents a unique advantage for large-scale applications. To fully unlock its potential, the introduction of desired functional groups onto the cellulose backbone is required, which can be realized by either chemical bonding or physical surface interactions. This review gives an overview of the chemistry behind the state-of-the-art functionalization methods (e.g., oxidation, esterification, grafting) for cellulose in its various forms, from nanocrystals to bacterial cellulose. The existing and foreseeable applications of the obtained products are presented in detail, spanning from water purification and antibacterial action, to sensing, energy harvesting, and catalysis. A special emphasis is put on the interactions of functionalized cellulose with heavy metals, focusing on copper as a prime example. For the latter, its toxicity can either have a harmful influence on aquatic life, or it can be conveniently employed for microbial disinfection. The reader is further introduced to recent sensing technologies based on functionalized cellulose, which are becoming crucial for the near future especially with the emergence of the internet of things. By revealing the potential of water filters and conductive clothing for mass implementation, the near future of cellulose-based technologies is also discussed.not suitable for drinking water treatment in rural areas or not applicable on a large scale. Other methods involving materials which have high adsorption capacities for pollutants, for example activated charcoal have been explored. [27,28] Nevertheless, there are no universal adsorbents for all pollutants, meaning that superior alternatives are still required. In recent years, biodegradable adsorbents such as cellulose and chitosan have attracted much attention for the removal of heavy metals.In particular cellulose has a number of advantages, which include high abundance, low cost, easy access, nontoxicity and biodegradability. It is particularly suited for the removal of low concentrations of heavy metals which occur in contaminated ground or tap water. [26] Beyond the aspects of copper removal from water, in this review we indicate how the metal's increased toxicity for microbial life can present an advantage for medical applications. Moreover, we also take a closer look at further applications of functionalized cellulose, including catalysis and sensing, which can make a great impact regarding energy conversion and management. The inclusion of conductive cellulose sensors within the internet of things global network is of particular interest, since an accurate weather forecast can provide swift adjustments in the usage of the often intermittent renewable energy sources. In order to understand what confers functionalized cellulose its versatility for broad applications, we first exemplify the functionalization techniques on a molecular basis.
