d="par0005">We report a facile approach to prepare cellulose/TiO₂/PANI composite nanofibers that involves P&ndash;N heterojunctions.

d="par0010">The response values and sensitivity of cellulose/TiO₂/PANI were much higher than those of cellulose/PANI composite nanofibers.

d="par0015">Enhanced sensing was obtained due to the P&ndash;N heterojunctions whose depletion layer would be widened when the sensor was exposed to ammonia.
