How do dissolved gases affect the sonochemical process of hydrogen production? An overview of thermodynamic and mechanistic effects – On the “hot spot theory”

A semi‐empirical approach for determining the number density and void fraction of acoustic cavitation bubbles in sono‐reactors

“…Many leading research groups in sonochemistry have used the single bubble approach to explain the overall reported sonochemical effects (sonoluminescence and sonochemistry) in aqueous solutions in connection to influencing factors. 23,27,[30][31][32][33][34][35][36][37][38][39][40][41][42][43][44][45] The reaction pathways employed for the internal chemistry of argon, oxygen, and air bubbles are shown in Tables S2-S4, respectively. Briefly, Table S1 regroups the following main equations:…”

The importance of chemical mechanisms in sonochemical modelling

“…Note that the vertical axes are on logarithmic scale. Hydrogen is of keen interest in sonochemistry and its production has become a very appealing topic lately [88] , [87] , [89] . It is apparent that the chemical yield intensifies radically at around (where the threshold for sonochemical activity is reached) with all four models.…”

An alternative technique for determining the number density of acoustic cavitation bubbles in sonochemical reactors

“…The involvement of this phenomenon in computation will be studied in future project. However, many leading research groups in sonochemistry have adopted the single bubble approach (without bubbles interaction) for understanding the overall observed sonochemical effects (sonoluminescence and sonochemistry) in aqueous solutions, with relation to influencing factors [42] , [63] , [64] , [65] , [66] , [67] , [68] , [69] , [70] , [71] , [72] , [73] , [74] , [75] , [76] , [77] , [78] , [79] . Table 2 , Table 3 show the reaction mechanism used to study the internal bubble chemistry for an Ar-CCl 4 -bubble ( Table 2 , 31 reversible reactions) and an O 2 -CCl 4 -bubble ( Table 3 , 29 reversible reactions).…”
