Perspectives of spray pyrolysis for facile synthesis of catalysts and thin films: An introduction and summary of recent directions

• We summarize important spray pyrolysis (SP) parameters.
• Recent developments in several SP-related fields are reviewed.
• Conclude spray pyrolysis as a facile method for controllable synthesis.

In the modern technological world, applications are rapidly demanding homogeneous, reproducible, scalable processes for films and catalytic surfaces. The uses of spray pyrolytic methods for fabricating these films have received attention since the late 1980s, and today spray pyrolysis finds use in a variety of applications, ranging from biomedical to industrial, microelectronics to ceramics. In this review, basic parameters of spray pyrolysis for catalytic and thin film formation are summarized, while recent developments in spray deposition for environmental remediation, photovoltaics, fuel cell and battery materials, biomedical applications, and microelectronics are also discussed.
