Special Issue Information
Dear Colleagues,
Semiconductor metal oxide is a popular and important gas-sensitive material with applications in public safety, pollution monitoring, breath analysis, smart homes and automobiles. Metal oxide semiconductor nanomaterials, such as SnO2, ZnO, VO2, In2O3, WO3 and CuO, have a high sensitivity, short response/recovery time and low cost considering their large surface-area-to-volume ratio and activity. Obvious depletion layer form on the surface of nanomaterials when gas absorbs there. The sensitivity of nanomaterials can be improved by reducing them to an ultrathin nanosheet or ultralong nanowire composite with another metal oxide or noble metal to form a heterojunction. These strategies can increase the ratio of the depletion layer on the nanomaterial and produce new functional materials for high-performance device or sensor applications.
Significant efforts thus far have focused on the synthesis and characterization of metal oxide nanostructures, such as ultrathin nanosheets, nanowires, nanoparticles, nanorods and so on. Many of these have been used to fabricate composite structures, for example, nanoparticles on nanowire or nanorods, cross-linked nanowire, vertical nanosheet arrays, etc. The underlying physics of nanomaterials and their possible applications in various gas detections, electronic nose and chemiresistive gas sensors have attracted the attention of both theorists and experimentalists.
The present Special Issue aims to collect state-of-the-art work on semiconductor nanomaterials and their homo- or heterojunctions considering both fundamental and application perspectives. Review articles or research papers dealing with the fabrication and the gas sensing properties of semiconductor nanomaterials and their heterojunctions are welcome.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Nanomaterials is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2900 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
