In this work, the porous g-C₃N₄ nanosheet with enhanced photocatalytic performance can be easily obtained using a “two step” strategy by treating melamine with organic acids and aldehydes. The photocatalytic performance of the samples was evaluated by the formation of carbon dioxide from formaldehyde under LED lamp irradiation. The photocatalytic activity of porous g-C₃N₄ nanosheet was improved significantly which the possible mechanism is that formaldehyde molecules are more easily adsorbed around the hole. This behavior reduces the carrier diffusion distance and increases the probability of photocatalytic reaction. The photocatalytic activity provides many reactive sites for formaldehyde.

在这项工作中，可以通过“两步”策略通过用有机酸和醛处理三聚氰胺来轻松获得具有增强的光催化性能的多孔gC ₃ N ₄纳米片。通过在LED灯照射下由甲醛形成二氧化碳来评估样品的光催化性能。多孔gC ₃ N ₄纳米片的光催化活性得到显着提高，其可能的机理是甲醛分子更易于吸附在孔周围。这种行为减少了载流子扩散距离，并增加了光催化反应的可能性。光催化活性为甲醛提供了许多反应性位点。
