Please help me analyze the results and discussion of catalyst characteristics in the BET isotherms of Cu-Ni/CeO2 catalysts.

Catalyst	BET Surface Area (m2/g)	t-Plot external surface area (m2/g)	Total pore volume (P/P0 = 0.95) (cm/g)
Ni/CeO2 reduced	19.51	15.633		0.064
1% Cu-Ni/CeO2 reduced	24.74	22.266		0.087
2% Cu-Ni/CeO2 reduced	30.35	27.478		0.084
3% Cu-Ni/CeO2 reduced	23.45	21.885		0.075
4% Cu-Ni/CeO2 reduced	34.22	31.595		0.087
5% Cu-Ni/CeO2 reduced	42.13	40.852		0.102
