Microwave-Assisted Xylose Conversion

All experiments were conducted using a microwave reactor (Anton Paar Monowave 400, Graz, Austria). The xylose and the catalysts in different concentrations were charged in the 10 mL glass vessel. The reaction volume was 4 mL; the xylose concentration was 30 g/L; and the catalysts used were H₂SO₄ at 2% w/v acting as Brønsted acid and FeCl₃ as Lewis acid, with a variable concentration [10 (link),13 (link)].
The heating dynamic followed was to heat the sample to the set temperature in 2 min, maintaining the temperature for the experiment time, and cooling down to 40 °C with compressed air. The magnetic agitation during the heating and maintenance was 600 rpm, and it was 800 rpm during the cool down period. The temperature was measured by an IR sensor (Anton Paar Monowave 400, Graz, Austria). The pressure inside the glass vessel was also monitored throughout the experiments, through the septum that covers it. The experimental conditions were set based on previous experiments not included.

The Sb-doped SnO₂ supports, which exhibited high electric
conductivities, were used for electrochemical measurements. Pt nanoparticles
were deposited on the Sb-doped SnO₂ supports via the colloidal
method,^{59 ,60 (link)} which consisted of two main steps: preparation
of a colloidal suspension of Pt nanoparticles via an alkaline EG route
and subsequent loading of the nanoparticles onto the SnO₂ support. The colloidal suspension of Pt nanoparticles (ca. 2 nm
in diameter) was prepared by mixing 4 mL of solution of 0.4 M NaOH
in EG with 4 mL of solution of 40 mM H₂PtCl₆·6H₂O in EG in a microwave reaction vessel and subsequently
heating the mixture for 3 min at 160 °C with a microwave reactor
(Monowave 400, Anton Paar) while stirring at 600 rpm. Pt nanoparticles
were loaded onto CMSbTO as follows: 91.5 mg of CMSbTO powder was added
to a colloidal suspension of Pt nanoparticles, and the suspension
was stirred at room temperature overnight. Then, 0.25 mL of 1 M HNO₃ was added to the suspension and stirred for 1 h. This process
was repeated four times. The suspension was then filtered, washed
with DI water, and filtered again. The residue was dried at 80 °C
in a vacuum oven for 2 h to obtain Pt/CMSbTO electrocatalyst powder
with a Pt loading of 20 wt %. A Pt/SSbTO electrocatalyst was also
prepared using the colloidal method, in which the Pt loading was controlled
to be 12.5 wt %.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
