“…Then, it decreased gradually, which was mainly attributed to the instability of HMF in acidic aqueous media towards further rehydration to form among others LA 67,68 as well as polymerization to form humins. 69,70 Notably, the decrease rate of the HMF yield in the presence of [Bmim]Cl was slower than in the absence of [Bmim]Cl (Fig. 2a).…”

“…Moreover, Zhang et al 107 also have investigated a novel class of molecular sieves known as silicoaluminophosphates (SAPOs), which showed a unique cubical crystal structure, as shown in Figure 12, high specific surface area, controllable acidity and pore sizes, and high thermal and hydrothermal stability for catalytic reaction in HMF synthesis under GLV/water medium reaction solvent. Liu et al 113 also investigated the use of microporous sulfonic functionalized SAPO‐34 as the catalyst for the fructose‐to‐HMF dehydration. The sulfonic functionalized SAPO‐34 catalyst exhibited excellent hydrothermal stability due to the acidic properties and the dispersion of the sulfonic acid on the surface of SAPO‐34 for direct contact with the fructose for the dehydration of fructose to HMF.…”

In recent years, researchers have gained attention in finding new strategies for alternative renewable energy resources in reducing the dependency on fossil fuel in providing energy to the world. 5-Hydroxymethylfurfural (HMF) is one of the most promising chemicals as it is a multi-functional compound and an intermediate compound that is beneficial in numerous chemical and fuel applications. This study provides recent progress on developing high yield and selectivity of HMF using hydrothermal reaction, emphasizing the catalytic performance efficiency of the developing structured catalysts from a technical perspective. We highlighted a few critical factors and parameters in maximizing the synthesis of HMF by selectively optimizing the desired kinetic reactions, which are hydrolysis, isomerization, and dehydration of sugars, and limiting the undesired side reactions, including HMF rehydration and depolymerization. The use of different types of microporous and mesoporous catalysts provides different HMF conversion results, and by applying few parameters, including catalyst: substrate ratio, Lewis: Brønsted acid ratio, reaction temperature, and duration of reaction, can be tunable in achieving maximum HMF yield and selectivity.

“…A variety of methods have been used to incorporate mesopores into SAPOs, which can be divided into two categories. Top-down methods create mesopores postsynthetically into a microporous SAPO, typically focusing on acid or base treatments, partially eroding the microporous network to create the mesopores. , In contrast, bottom-up methods form mesopores alongside the microporous framework, during synthesis, typically through a mesopore template, that is included in the synthesis gel. “Soft” templates are hydrocarbons that can be removed on calcination, along with the microporous SDA, leaving larger pores behind (Figure ).…”

Word 2010, single-column, double-spaced (2013)This template is a guide to be used to prepare manuscripts for submission. Please consult the Instructions to Authors or a recent issue of the journal for detailed guidelines and procedures for submission. This template is intended to benefit to the author in that the entire manuscript (text, tables, and graphics) may be submitted in one file. Inserting graphics and tables close to the point at which they are discussed in the text of the manuscript can also be a benefit for the reviewer.When you submit a manuscript using this template, you will not actually see the page formatting that appears in the printed journal. This will occur as part of the editorial production process. Abbreviated instructions for using the template follow. Consult the documentation for your specific application and version for more information. Additional instructions can be found in the readme file at the web page where you downloaded this template. Using the templateIn ACS publications there are many different components of a manuscript (i.e., title, abstract, main text, figure captions, etc.) that are represented in the template. See the Guide, Notes, Notice, or Instructions for Authors on the journal's homepage to determine which parts should be included for the manuscript that you are preparing 1. If typing your manuscript directly into the template, select (highlight) the text of the template that you want to replace and begin typing your manuscript (i.e., select the Title section for typing in your title).2. If you have already prepared your document in a Word file, you will need to attach the template to your working document in order to apply the Word Style tags. Further instructions can be found in the readme file at the web page where you downloaded this template.a. Go to the Add-Ins tab and you will see all the Word Styles from the template that has now been imported into the current document. A Styles toolbar has been generated that will display the different Styles for you to choose from. If this is not present, type in the following command (Alt+Ctrl+Shift+S) and it should appear. You can close this at any time and then reopen it when needed.b. Click in the sentence or paragraph and then go to the Add-Ins tab and select the relevant Word Style. This will apply the Word Style to the entire text (sentence or paragraph). Do this for all sections of the manuscript.3. To insert graphics within the text or as a figure, chart, scheme, or table, create a new line and insert the graphic where desired. If your graphic is not visible, ensure that the Word Style is "Normal" with an automatic height adjustment. If the size of the artwork needs to be adjusted, re-size the artwork in your graphics program and re-paste the artwork into the template (maximum width for single-column artwork, 3.3 in. (8.5 cm); maximum width for double-column artwork, 7 in. (17.8 cm)). NOTE: If you are submitting a Table of Contents graphic, please insert the graphic at the end of the file.4.
