2.1. Synthesis of g-C 3 N 4 from melamine g-C 3 N 4 was synthesized directly from melamine (99% Sigma Aldrich) via a solid-state thermal polycondensation reaction procedure. The white precursor was heated at 500 1C for 15 h in static air (i.e. heating rate: 5 1C min À1 ) in an alumina crucible covered with aluminum foil. 33 2.2. Impregnation of gold on g-C 3 N 4 through the deposition-precipitation method using urea (DPU)
A slurry of g-C 3 N 4 (10 g L À1 ) was prepared in a solution containing HAuCl 4 Á3H 2 O (50 mL, 99.9% Sigma Aldrich) of 1.07 mM for a 2.1 wt% gold loading and urea (99%, Fisher Scientific) (i.e. from 0 to 0.85 M). The slurry was stirred (500 rpm) at 85 1C for 1, 4, 8, or 16 hours. The slurry was then filtered and washed with 500 mL of deionized water before being dried overnight at 80 1C, forming the as-prepared Au/g-C 3 N 4 . A thermal treatment was performed at 300 1C for 1 hour (i.e. heating rate: 5 1C min À1 ) either in static air, or under a flow of 5 vol% H 2 in argon.

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.
