The embodiments herein provide a system and a method for synthesizing graphene-supported photocatalytic nanomaterials for air purification. The method includes synthesizing a ceramic substrate from aceramic material in particulate form; depositing carbon material on the synthesized ceramic substrate; depositing one photocatalytic nanomaterial on the carbonaceous material coated ceramic substrate;transforming the phase of the ceramic substrate coated with carbonaceous photocatalytic nanomaterial in inert atmospheric condition from one phase to another phase; and activating the transformed ceramic substrate coated with carbonaceous photocatalytic nanomaterial, when exposed to photo energy source. 本文的实施例提供了用于空气净化的石墨烯负载光催化纳米材料的系统和合成方法。所述方法包含：由颗粒状的陶瓷材料合成陶瓷基板；在合成的陶瓷基板上沉积碳质材料；在涂覆有碳质材料的陶瓷基板上沉积一种光催化纳米材料；在惰性环境条件下，将涂覆有碳质光催化纳米材料的陶瓷基板的相态从一种相态相变为另一种相态；以及当暴露于光能源时，对相变后的涂覆有碳质光催化纳米材料的陶瓷基板进行激活。
