Table 1. Relative pH and concentration of CH₃OH (upper gas) at different ripening times.

	T a = –3 h	T b = 0 h	T = 24 h	T = 48 h
pH	3.90	2.25	1.83	1.82
CH3OH (%)	0	0.657	0.742	0.759

^aRefers to the initial stage before the addition of the Na₂PdCl₄ aqueous solution during the synthesis of sacrificial nanocrystals.

^bRefers to the beginning of the ripening-mediated growth.
