However, the capacity decays seriously because of poor conductivity and severe volume expansion. Designing nanostructures combined with carbon are effective means to improve cycling stability. In this work, ultra-small Fe2O3 nanoparticles loaded on a carbon framework were synthesized through a one-step thermal decomposition of the commercial C15H21FeO6 [Iron (III) acetylacetonate], which could be served as the source of Fe, O, and C. As an anode material, the Fe2O3@C anode delivers a specific capacity of 747.8 mAh g\u22121 after 200 cycles at 200 mA g\u22121 and 577.8 mAh g\u22121 after 365 cycles at 500 mA g\u22121. When selenium powder was introduced into the reaction system, the FeSe2 nano-rods encapsulated in the carbon shell were obtained, which also displayed a relatively good performance in lithium storage capacity (852 mAh g\u22121 after 150 cycles under the current density of 100 mA\u00b7g\u22121). This study may provide an alternative way to prepare other carbon-composited metal compounds, such as FeNx@C, FePx@C, and FeSx@C, and found their applications in the field of electrochemistry.<\/jats:p>","DOI":"10.3390\/molecules27092875","type":"journal-article","created":{"date-parts":[[2022,5,1]],"date-time":"2022-05-01T06:23:08Z","timestamp":1651386188000},"page":"2875","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["One-Step Route to Fe2O3 and FeSe2 Nanoparticles Loaded on Carbon-Sheet for Lithium Storage"],"prefix":"10.3390","volume":"27","author":[{"given":"Denghu","family":"Wei","sequence":"first","affiliation":[{"name":"School of Materials Science and Engineering, Liaocheng University, Liaocheng 252059, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Leilei","family":"Xu","sequence":"additional","affiliation":[{"name":"School of Materials Science and Engineering, Liaocheng University, Liaocheng 252059, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhiqi","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Materials Science and Engineering, Liaocheng University, Liaocheng 252059, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaojie","family":"Jiang","sequence":"additional","affiliation":[{"name":"School of Materials Science and Engineering, Liaocheng University, Liaocheng 252059, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaxia","family":"Liu","sequence":"additional","affiliation":[{"name":"School of Materials Science and Engineering, Liaocheng University, Liaocheng 252059, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuxue","family":"Ma","sequence":"additional","affiliation":[{"name":"School of Materials Science and Engineering, Liaocheng University, Liaocheng 252059, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jie","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Materials Science and Engineering, Liaocheng University, Liaocheng 252059, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,4,30]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"652","DOI":"10.1038\/451652a","article-title":"Building better batteries","volume":"451","author":"Armand","year":"2008","journal-title":"Nature"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"830","DOI":"10.1021\/acsnano.8b08344","article-title":"Constructing Heterointerface of Metal Atomic Layer and Amorphous Anode Material for High-Capacity and Fast Lithium Storage","volume":"13","author":"He","year":"2019","journal-title":"ACS Nano"},{"key":"ref_3","doi-asserted-by":"crossref","first-page":"15969","DOI":"10.1039\/C9TA04062E","article-title":"A novel strategy for the synthesis of highly stable ternary SiOx composites for Li-ion-battery anodes","volume":"7","author":"Guo","year":"2019","journal-title":"J.
