Abstract

A copper-based catalyst which is suitable for converting ammonia of high concentration and with better selectivity, thereby solving a problem of pollution and toxicity due to nitrogen oxides by a conventional catalyst reacting under high temperature is disclosed. The copper-based catalyst comprises: a porous oxide support and a low valent copper compound mixing with the porous oxide support by an acid hydrothermal method; wherein the low valent copper compound with is Cu and Cu 2 O.

Claims (7)

1. A copper-based catalyst for converting ammonia into nitrogen comprising:

a porous oxide support;

a low valent copper compound; and

derivatives of copper aluminum oxide,

wherein the porous oxide support adheres to the low valent copper compounds with a weight percentage of 39.61%, and

wherein the low valent copper compound is Cu and Cu 2 O, wherein the derivatives of copper aluminum are according to the formula CuAl x O y .

2. The copper-based catalyst for converting ammonia into nitrogen as defined in claim 1 , wherein the porous oxide support is aluminum oxide clays or zeolites.
