Abstract
With the advancement of nanomaterials science and technology, metal oxide semiconductor (MOS) has been extensively explored to develop high-performance gas sensors for various applications, especially in environmental protection, chemical industry, food safety, and disease precaution. Among various nanostructure, porous MOS materials have garnered significant attention for their outstanding features including abundant interconnected pores, numerous active sites and high specific surface area, which are particularly favorable to enhance gas–solid interactions in gas sensing. The non-ionic surfactant templates are commonly used to synthesize porous MOS because they can precisely control the porous parameters including pore structure, size, wall thickness and the pore wall surface chemistry. This review aims to present a thorough and critical analysis of the advancements and current state of porous MOS sensitive materials synthesized by non-ionic surfactant template, focusing on their designed synthesis, gas sensing performance and novel mechanism. The classification and definition of common non-ionic templates in the field of gas sensing are summarized, and the advantages of non-ionic templates in the synthesis of porous MOS are discussed. By virtue of the porosity of the as-synthesized high-crystallinity MOS materials, the sensitization strategies of porous MOS materials, including noble metal sensitization, heteroatom doping, heterojunction design, and multicomponent recombination, were also systematically reviewed and discussed. Lastly, we summarized the development trends and challenges of porous MOS sensitive materials synthesized by non-ionic template.
期刊介绍：
Progress in Materials Science is a journal that publishes authoritative and critical reviews of recent advances in the science of materials. The focus of the journal is on the fundamental aspects of materials science, particularly those concerning microstructure and nanostructure and their relationship to properties. Emphasis is also placed on the thermodynamics, kinetics, mechanisms, and modeling of processes within materials, as well as the understanding of material properties in engineering and other applications.
The journal welcomes reviews from authors who are active leaders in the field of materials science and have a strong scientific track record. Materials of interest include metallic, ceramic, polymeric, biological, medical, and composite materials in all forms.
Manuscripts submitted to Progress in Materials Science are generally longer than those found in other research journals. While the focus is on invited reviews, interested authors may submit a proposal for consideration. Non-invited manuscripts are required to be preceded by the submission of a proposal. Authors publishing in Progress in Materials Science have the option to publish their research via subscription or open access. Open access publication requires the author or research funder to meet a publication fee (APC).
Abstracting and indexing services for Progress in Materials Science include Current Contents, Science Citation Index Expanded, Materials Science Citation Index, Chemical Abstracts, Engineering Index, INSPEC, and Scopus.
