Most of the polymer-supported metal catalysts have obvious advantages such as high catalytic activity

easy separation and purification of product after reaction and easy recovery and reuse several times without any remarkable loss in catalytic activity. Cellulose is one of the most abundant natural polymer on earth. It is stable in most organic solvents

has high surface area and hydroxyl functional groups that are capable of chelating to metal ions and particles thereby providing required stability. In addition

it is biodegradable

non-toxic and available at low price. In this paper

synthesis of cellulose- based metal catalysts and their applications in organic transformation were summarized.
