1. INTRODUCTION

The rapid growth in industrial production accompanied by marked ecological deterioration requires the development of highly sensitive and selective sensors for the detection of a variety of pollutants in the atmosphere. Conductometric chemical sensors based on nanocrystalline metal oxide semiconductors are the most promising of solid-state gas detectors due to their reliability, and ease of manufacture and application. The small size and relatively ...
