1. A method for producing a photocatalyst for degrading NOx, comprising,
(a) mixing a transitional metal or an oxide thereof with a solvent at a ratio of 1:10 w/v to produce a first mixture;
(b) mixing a bone powder or a shell powder with the first mixture of step (a) to produce a second mixture, in which the bone powder or the shell powder and the transitional metal or the oxide thereof are present in the second mixture at a weight ratio of 1:1 (w/w);
(c) heating the second mixture of step (b) to produce a dehydrated product; and
(d) calcinating the dehydrated product of step (c) to produce the photocatalyst.
